Have you talked to your school guidance counselor? I had to w/draw from a semester due to mental illness. They put a medical withdrawal and I didn't loose my financial aid. Try looking into that. I ended up taking a year or two off, got on the right meds, and went back to finish.

It happens. Get yourself better, that's more important then anything else.

Your mom may or may not understand. Don't let that sress you more.
