I'm glad you're trying the positive thinking thing, it does help over time
I'm sorry about the sleeping, is it getting any better? I myself have been having trouble with that latley. I tried to stay up past 24 hours to reset the clock but stayed up until 6am last night/morning. Oh well. College can get so difficult. Sadly, you have to get yourself better before you can function in school. I ran into this problem last semester. I didn't take care of myself first - I tried pushing through school and I ended up not being able to handle it because they put me on meds and everything went boom. I hope this does not happen to you. My advice would be to put first priority on figuring out the meds. Try to get a list of the most important classes for you to take right now and only work on them. If you miss one class this semester, you hopefully can make it up later - you're going for at least finishing the semester and getting better so the next can be killer.
have to go for now , sorries, rl calls
