try doing an online bipolar quiz, and after the results from that print it out and take it to a doctor. remember just dont use this as diagnosing urself. Your doctor will then look at it and then do his/her own evaluation on you and will determined for sure if this is what you have.
Bipolar disorder is the new term used for manic-depressive. Some of your symtoms could indicate a problem. I would definitely recommend seeing a mental health provider who will be able to make a rational evaluation as long as you're truthful about all of your symtoms. There are many new medications that can help. If you are bipolar realize that it is incurable, but controllable. See someone soon abd good luck.
I was under the impression that bi-polar disease skips a generation. You can get your blood chemistry tested and then you will know for sure. My mother was bi-polar and on Lithium and other drugs all her life. There was never a question of whether she was bi-polar.
There isn't a standardized blood test available to check for bipolar disorder yet. (I am not sure I would trust it even if it was available) The diagnosis is based on symptoms and determined by either a psychologist or psychiatrist.
The topic of the blood test for biological markers is interesting though.
