My school had a lot of support for struggling students. It's not cheating. Asking for help is hard (especially if you're a perfectionist like me) but it will save your sanity.

Your school should have a centre for students with disabilities, that might be a place to start. Or what we called the Learning Centre, they had a lot of resources for different learning strategies and peer tutoring. Perhaps the teaching style of your professors this semester doesn't mesh with your learning style? They can help with that.

Definitely talk to your professors, or TA. Can you email them if speaking to them is too stressful? I organize my thoughts better in writing. I also practice what I want to say. I find talking to authority figures incredibly anxiety producing, practicing helps.

Good luck to you
