Hey ydarb...

I have to agree with lightanddark...your symptoms sound a lot like depression...the apathy, lethargy, not caring for things you used to. The stress of trying to keep up at an elite university is plenty to bring on depression. You say you're being treated for ADHD...the combination of that and depression could suggest a form of bipolar...go talk to a doc, get a depression and a bipolar screening. Whatever you do, try to exercise, even though you don't want to. Keep us posted, OK? We're with you.
