I think I'm bi-polar, but I'm not sure..?!

I think I'm bi-polar, but I'm not sure..?

I have crazy mood swings where I am extremely overly excited about something and everyone else is just kind of excited and then any little thing will make me very upset. My boyfriend and I have been together for 2 1/2 years and for the past 1 1/2 we fought fought basically everyday. I mean he does a lot of things too.. but I know i blow a lot of things way out of proportion. How can I tell if I really am?

Go to a psychiatrist who can diagnose if you are bi-polar or not, or if it is something else. Thats the only solution.
