I know everyone has their own personal story, but I just wanted to give you some input about SJW:
My dad took it for awhile to relieve the "down in the dumps" feeling. My mother told me he had to stop because if he didn't continue taking it, it made him feel worse. I just want you to be careful when you take things because can you imagine feeling even more poopy??
Since you are enrolled in school, here are some things you can do to pick yourself up every now and then:
-go to counseling (yeah, we covered that)
-go to the health office to see if they can give you any insight of the BC
-work out at the on-campus facility (meet some people that go there regularly, AND working out released endorphins...those make you feel happy

)
-join some clubs (I don't mean psycho clubs but something you're genuinely interested in)
-join some study groups (if they are available...you maintain good relationships with people if you are all working on the same thing...it's a group mentality thing)
Good luck, and keep posting if that helps you- you've got a forum full of people here to listen to you.
