Are you in treatment for your anxiety? If not, you need to be - see a doctor pronto. I do mean now. You go to class tomorrow? Go see someone in the urgent mental health services at your student health center tomorrow.
See if you can get through the next three weeks. Get up, go to class, do the work - go on auto pilot. All while doing your treatment. Just get through the next three weeks. If that’s absolutely impossible, talk to your professors and to your advisor. See if you can submit the work from home, or get incompletes in your classes for medical reasons.
Talk to your school about getting a leave of absence for next semester. Do not return until your health issues are under control. During your LOA, you’re in treatment. If you feel you can handle it, you can also take classes at a local college, so you can continue to make progress toward your degree - but if that’s not realistic for you right now, then don’t do it. You can also look into transferring to a school closer to home, or one you can commute to from home.
You have severe health issues right now which are getting worse. Get into treatment now. And if what’s best for you is to transfer to a college near home, then do it.
