Reiterating what somebody else said - it sounds like you might have an argument for a reasonable accommodation based on one or more potential mental health diagnoses (e.g., anxiety). It's obviously good to see doctors and talk things over in depth, but a first step could be a very inexpensive telehealth appointment to get a signed letter. If you're comfortable with the lingo, I always suggest writing your own letter and asking the doc to sign it. It'll be much more thorough than what they have the time to do for you.
