Creative one gave a good synopsis of what bp is. All I can add is it is a life time disorder that does normally become worse with age. Sometimes the cycles come out of no where and can be very intense. I believe that most ppl have a tendency to demonstrate a particular mood more often then The other. At least I do and most I have spoken to shared they do. Sorry you found out that way. I would definitely have a pdoc to confirm and assess. Best of luck.
