Yes, it's a real issue and an ADA issue. And yes, the whole aspect of reasonable accommodations comes into play.
Here's something you might want to consider. What if you have an advocate present with you when you broach the issue? Or, what if you ask an advocate to send a letter or email on your behalf? An advocate can be a former teacher, former coach, potentially someone with ASAN (although that might be several years down the road), maybe a skills coach, etc.
If you just talk to them one on one, they might just come up with a reason to brush off the issue. That dynamic comes into play all the time. But with an advocate present, or writing on your behalf, they might take the whole thing more seriously, and seriously engage with the issue and try and come up with a solution.
One note, please don't lose a friend or relationship looking for an advocate. If you ask them snd they say no or aren't sure, try not to hold it against them.
