mentally unstable?

mm. it seems as though bipolar and depression don't mix too well. i am finding myself mixing through emotions while sitting down listening to others at lunch or during class. i am not speaking to them, nor are they confronting me to start a conversation, so there is absolutely no definite reason for why my emotions are jumping around. at the beginning of the day, before class, i would talk to this girl (who is not in fact talking to me for me, but for my friend, who she likes) who mkaes me smile and keps my mood up, but then i'll go to class and suddenly go into a very bad mood. (note: the girl who is isolating me is in this class... so that may affect the mood subconsciencely.) i'll get angery half way and start ripping up papers and then just go blank. i'll move through out my classes with these little moodswings, some more drasitic than others. afterschool when i go to work though; i just got angery for no reason and flipped over a chess board. (god knows why it was there.) then i left early. i felt much better after leaving, and a girl who was getting tax signatures sat down and talked to me, which lightened my mood, then when i got home i went back to my state of depression and my evening ended in a mixture of sadness and anger when i tried to get a hold of my writing partner who told me that i only ever think about myself. i havent eaten in days, just barely started studying for my finals, realising i'm going to fail big time, and i just finally looked in the mirror for the first time in a month; does she really think i've had time to think about myself when i'm busy caring about her? to be honest, she's a... well; i'm angery now, but i feel much better ranting.i could go on forever but i think i should stop now....i've once again forgot the point of this piece.
