It's called bipolar...don't let it getcha.
There are so many things to do...the most important is to get the treatment you need from a psychiatrist experienced in the treatment of bipolar depression. You need to get on the meds that can help you feel better, only a good pdoc can help with that. You need to be in therapy with a good psychologist. Attend a support group for those with bipolar disorder--look up your local DBSA or NAMI chapters, here are the links:
www.DBSAlliance.org and
www.nami.org.
Get some excercise every day, preferably out in the sun. Eat regularly, good meals. Regular sleep cycle, 7-8 hours at night. Get up and go to class even if it feels like you're going to die. As you walk to class, put your head up, shoulders back and smile! Act like you want to be here, even if you don't. Say "hello" or smile at people as you're walking. You'll feel a lot better when someone smiles back.
I know all this sounds crazy, but this is what I have to do get through the day. I don't get them all done every day, but I try. You can do it, one step at a time.
Take care of yourself...and if you feel that you don't want to take care of yourself anymore, please go to the emergency room...we care about you. PM if you want, I've been there.
