i'm 19 and i think that i have a bit of a mental problem, but i'm not too sure. I am aware that bipolar runs in my family. my father has it and his father had it, even though i am a girl i take after that side of my family alot and i think i might be suffering from bipolar. I'm a very cheerful person but at least once or twice a day i suddenly take a mood nose dive and become seriously depressed, so much so that i have taken to etching into my skin with a needle or crying hysterically for about thirty minuets to an hour. then once it has passed i am back to the over cheerful mood i was in previously. i'm not sure if this is something serious or hormones or what? i do admit though that i aslo do crave attention though and love being centre of attention, but when i have my sudden mood swings i can't handle being around people. the only people who can handle this is my family and only two of my frineds. What should i do? am i sufering from bipolar or something similar or am i just indirectly seeking attention?
