spent like two years convinced I had long covid or some mystery autoimmune thing. Saw three different doctors, got bloodwork done twice, tried elimination diets, bought expensive supplements. nothing helped. the fog just kept getting thicker

It wasn't until my sister sat me down and basically said "you know you drink every single night right" that I even considered it. and even then I got defensive. Because it's not like i was blacking out. just a few drinks to take the edge off. Every night. for years

Turns out your brain doesn't really care about the difference between "functional drinking" and "problem drinking" when it comes to cognitive function. Who knew lmao

Ended up taking some time away at discovery point retreat which is what finally cleared things up. not just the fog but all the anxiety underneath it that I was numbing in the first place. Six months later and I can actually read a book without re-reading the same paragraph 8 times

anyway not saying everyone's brain fog is alcohol related but if you're at the point where you're googling "brain fog mystery cause" and you also happen to drink regularly... maybe just take a 30 day break and see what happens. saved me thousands in supplements tbh

I'm a 21-year-old web developer, and I honestly feel like I've lost the last 7+ years of my life.

My biggest problem isn't motivation. I desperately want to work, but when I sit at my laptop my brain just shuts down. Technically I don't have motivation just i made it habit and discipline.

My symptoms:

• I sit for hours and get almost nothing done.
• I have severe executive dysfunction and time blindness.
• My processing speed feels extremely slow.
• My working memory feels almost nonexistent. I read something and it doesn't seem to stick.
• I constantly drift into rumination, self-analysis, or maladaptive daydreaming.
• Since childhood I've had intrusive fearful thoughts, and my brain immediately starts analyzing them instead of letting them go.
• Every self-help concept becomes an obsession. If I learn about mindfulness, I keep checking whether I'm present. If I learn about discipline, I keep checking whether I've lost self-control. My brain turns everything into another mental project.
• I keep searching for the "exact root cause" instead of actually living my life.

I've had extensive blood work (thyroid, B12, vitamin D, iron, glucose, CBC, etc.) and everything was normal.

I've tried:

• stopping music/daydreaming triggers
• self-help
• meditation
• spirituality
• productivity systems
• therapy advice
• psychiatrists

I'm currently 3+ weeks into Bupropion XL 150 mg + Clonidine (Arkamin) with essentially no noticeable improvement so far.

My clients keep waiting for work while I spend entire days trapped inside my own head. I genuinely feel like my brain can't process information or execute tasks anymore.

Please be honest, even if the answer isn't what I want to hear. I just want to know if someone with a similar story eventually got their life back.

I’m 35 years old and I’m trying to figure out if anyone has experienced something similar and eventually recovered enough to return to a successful career.

I was able to build what I considered a successful professional career. I earned two graduate degrees, worked my way into a high-paying corporate roles, and functioned well for years. Looking back, I believe stimulant medication (Adderall) played a significant role in allowing me to overcome lifelong attention difficulties, but it is no longer effective.

Over the last couple of years, however, my cognitive functioning has deteriorated to the point where I can no longer work.

My biggest symptoms are:

* Extremely slow processing speed.
* Severe attention and concentration problems.
* Reading comprehension has become incredibly difficult. I often have to reread the same sentence multiple times and still struggle to understand it.
* Conversations are exhausting because I can’t organize my thoughts or find the right words quickly enough.
* My brain feels mentally exhausted almost all the time, even after simple tasks.
* I feel disconnected from other people because it’s so hard to participate in conversations.
* Interviews and complex work tasks have become nearly impossible.
* Even everyday activities require much more mental effort than they used to.

I completed a neuropsychological evaluation. My results showed significant attention deficits, while many other cognitive areas were relatively preserved. Anxiety and depression are also present, but I personally feel that my attention and processing problems are driving much of my emotional distress rather than the other way around.

I’ve been working with both a psychiatrist and a therapist. I’ve tried different medications, but I still haven’t found anything that restores my ability to function the way I once could.

At this point I’m unable to work and am considering applying for disability because my cognitive symptoms have become so disabling.

I’m wondering:

* Has anyone experienced something similar?
* Were you eventually given a diagnosis that explained it?
* Did any treatment significantly improve your attention, processing speed, or reading ability?
* Were you able to return to your previous career or build a new one?

I’m especially interested in hearing from people who went from being highly functional in demanding careers to feeling like their brain simply stopped working the way it used to. Success stories would mean a lot right now.

Thank you for reading.

15 year old male with years of unexplained fatigue, brain fog, and delayed puberty signs. Looking for possible causes or what should be investigated next.

Hi! I'm a 15 year old male from the Philippines. I've been experiencing persistent low energy and brain fog since around Grade 5, and it's still affecting me now in Grade 11. The symptoms are present almost every day and have significantly affected school, sports, and social life.

Main symptoms

\- Chronic fatigue / very low energy almost every day

\- Brain fog (slow thinking, poor concentration, reduced mental stamina, difficulty finding words)

\- Wake up tired even after 7.5–8 hours of good-quality sleep

\- Exercise intolerance (get tired much faster than friends)

\- Low physical strength

\- Social activities also drain my energy

\- Dark circles under my eyes that don't improve much even with enough sleep

\- Cold hands and feet sometimes

\- Occasional mild lightheadedness when standing (used to be much worse before)

Puberty concerns

\- 15 years old

\- No armpit hair yet

\- Very little body hair

\- Often mistaken for someone much younger than my age

\- Baby face / younger appearance compared to classmates

Things that DON'T seem to explain it

\- Food doesn't noticeably improve the fatigue.

\- Water doesn't noticeably improve it.

\- Coffee only helps a little, if at all.

\- Lying down or resting usually doesn't restore my energy.

\- Sleep is usually deep and uninterrupted.

Recent laboratory results

\- CBC: Normal (Hemoglobin 15.2 g/dL)

\- Iron studies: Normal

\- Ferritin: 648 (possibly elevated from previous iron supplementation and/or recent illness)

\- Vitamin B12: 738

\- TSH: 4.09 (upper end of normal/borderline high)

\- Free T4: Normal

Other information

\- Previously had low blood pressure.

\- I have POIS (Post-Orgasmic Illness Syndrome), but my baseline fatigue continues even after reducing ejaculation, so it doesn't seem to fully explain everything.

\- My pediatrician referred me to a hematologist, but I'm wondering if an endocrine problem should also be investigated.

My questions

1. Based on this history, what conditions would be highest on your differential diagnosis?

2. Would delayed puberty or hypogonadism be a reasonable possibility?

3. Should I be evaluated by a pediatric endocrinologist?

4. What additional blood tests or imaging would you recommend?

Thank you for taking the time to read this. Any advice or ideas would be greatly appreciated.

So it's hard to identify what is actually causing the Brian fog.

It all started in 2024 when I was just studying stressed out as I had my exams next month. I was just studying and a random complex thought appeared in my mind related to something why. It was a why thought and that's normal we all face it during our day to day lives however this time it wasn't going it was just stuck into my mind.and just soon after that I started facing these thoughts daily. Then I somehow gave my exams and got good grades however after sometime I started having forehead pressure too much that I started feeling disconnected from the environment then I don't remember properly that afterwards or soon after that I also faced brain fog .

Now I went to ent but that doesn't work out so i decided to do chatgpt and search thru reddit.

Now as I started searching through them I don't know my anxiety just got worse Whatever symptoms I used to see I start having those in myself and till now I was just convinced that something was off in me like I was having some serious issue instead of anxiety that's what I started thinking. Also, on reddit I started seeing people facing this issue for more than 5 years or 10 years so I just convinced myself that there is no solution to this issue. The problems I start facing were:

2025

Blurred/double vision

Forehead pressure (worse in public places)

Not able to think properly

No fun in any thing

Tingling sensations

Throbbing pain in legs

Burning sensations in stomach

Vibrating stomach

Gut issue

Not able to articulate sentences properly

Was hard to understand a simple sentence

Simple word used to be harder

I was running my brain on manual mode

These are the symptoms I remember there might be more

Now, during this period I have been to the doctor (physician) who prescribed me a test which I went for and found out that my vit d levels were low (deficit). And my vit B12 were in normal range but at the baseline . He only prescribed me a single test CBC.

So I started taking VIT d supplement each week one tablet and eventually my deficiency was covered and now things got better not completely but there was improvement but again they got worse and this whole thing ruined my studies and many aspects of life .

Before this I was a guy with good grades goo d thinking and ambitious my now it feels like I am useless and will be for rest of my life.

Symptoms I facing now or I am left with :

Brain fog ( that is fluctuating sometimes extreme sometimes too low )

Tight neck

Upset stomach

Vibrating tummy

Double vision and forehead pressure ( they both also vary sometimes too much sometimes mild )

So i just want to ask what can be the rela issue the reason I have written this much is to know what can be the actual issue I don't want to go to the doctors and coming back knowing nothing I really want to get better atleast 80%. 20m turning 21 next month facing these symptoms from the age 19

Thank you
