I just faced the same situation this week. I recently was diagnosed, and was taking a course at the time. I missed a bunch of time while I was in a hypomanic state. I dropped the course and since my school had 5 week courses, I figured I could restart as soon as my meds were all set. A few months later, still adjusting meds, I decided to try and go back. Week 2 of the class I have another episode and I'm back to the point staying or going. In calling my academic advisor and mentioning some of what is going on, In was referred to the Student Disabilities Office. To save my GPA, could go on hold again, but I don't want to take it again. So I talked to the SDO and they can advocate on your behalf with the profs, extra time on tests and assgnments.

If you stay in this semester find your college's Student Disability Office, they can help you get back on track. I've also had a harder time studying on the meds. Before it took little effort, now it's like I have to force it.
