How do i know if i really have bipolar disorder
You go to a psychologist.
Ask your doctor. :-/
How do you feel now and how did you feel five minutes ago.
If you go from one mood/behavior to another within a small amount of time
If you have bi-polar the doctor will order blood tests i believe once a month. Bi-polar is actually a medical condition, you just have a chemical imbalance in the brain (salt) good luck
