My Tongue

I haven't posted in this sub for a while so I apologize for the length. I'm just not sure what to do anymore. I posted quite a few times over the past few months before but am getting desperate about this. Some say there's no such thing as a disability to learn a language and others say yes. I was leaning on the idea that there was no thing until I started taking Thai classes on italki about three or four months ago. I also took two hours one time from a Vietnamese teacher and just could not pronounce anything at all. <br><br><br><br>The problem is my tongue. It is way too big, so it can't fit with my normal teeth so I've had to get a lot of my teeth pulled. My teeth puller (dentist) said I would be able to swallow my tongue too because of its size. She recommended I visit an oral surgeon for a tongue reduction. I tried to fill out the intake form for the oral surgeon but they don't take any insurance. It's a lot of money for me, so it's not worth it for the sake of learning a language. <br><br><br><br>Someone on Chambers said my soft palate is the problem, not the tongue. I've never heard of this before, and the dentists I visited never recommended an operation on it. It's hard to find anyone who can comment on it. Maybe I should go to another dentist, but I've never heard of such a thing before. <br><br><br><br>I've been trying to practice the pronunciation in Thai lessons, but it's not getting better. I have to overthink every sentence so much over the way my tongue is positioned. I am very much wondering if this is a learning disability. Some say it is, others say there's no disability to learning a language, so what do you think?
