Here's the situation, all I want is some input on what to do.... since I don't know....

I have Depression and this semester has gone like this....
First week, in the mental hospital
Second through sixth week, able to go to class...
Half way through Sixth week to middle of seventh week... in the hosptial again

I just got out of the hosptial two days ago

I am taking General Chemistry (2nd half), Physics (2nd half 112), Labs for both classes, Band, and Abnormal Psychology

I'm almost done with Abnormal Psychology, one more week and then the final.... and the rest....

General Chemistry- I'm struggling with the concepts
Physics- haven't read through the chapters
Band- that one I could stay in even if I drop out

What would you do, in my situation?
