I might be super lucky and gone to a great college. But I worked with the student accessibility department and all my professors except a couple were more than willing to work with me. Giving me an option to present to just them during office hours, write an essay instead of presenting, etc. I’d look into that if you really are struggling and it’s impacting your ability to learn. If not, you’re a braver person than I am. Go for it. I’m sure you’ll only get more confident and feel great after.
