I've posted on here and r/opera. People have been overall very supportive with a bunch of different takes on what my voice type is (understandable in hindsight although a bit funny) as well as different takes on my issues (all of these were correct just of different orders of importance).
I saw great improvement in my first year and a half of lessons, but as time went on I felt like I was stalling in both range and volume, and with no vibrato to be found. By almost 4 years in a combo of peoples here reaction to my voice (that it sounds like I'm holding back or crooning) in combination with friends suspicious that something was up I was getting a gut feeling something was wrong and it just wasn't technique.
Saw an SLP in oct 2025, turns out I do have tension issues she gave me tongue and larynx stretches and both helped a bit but thought nothing was wrong on the fold level but 6 months later I still had a gut feeling something was wrong so I got a stroboscopy and learned I have incomplete closure... due to vocal fold atrophy. That is specifically atrophy of the thyroarytenoid muscle (which explains why so many people online think I'm a tenor).
I'm now seeing a better SLP focused on singing and speaking voice rehabilitation and while I may need thyroplasty, for now I am focusing on dealing with tongue retraction and tongue tension which has likely been "helping" me phonate, and forcing closure and not giving the TA a chance to work. I've already noticed improvement.
All this yapping basically to say that as Jerome Hines says in his The Four Voices of Man, the singer themselves is the first to know that something is wrong with their voice, and I agree. Trust your gut. If I went based off of my teachers advice or even the first SLP I would probably be masquerading as an overly quiet "bass-baritone" with mix highs getting called a tenor and never being able to sing with orchestra.
Trust your gut.
