How would you know if you'r bipolar?

When: There are mood swings of depression and then mania( hyperactivity) in mood.

See a psychiatrist: You should not try to diagnose your own psychiatric problems, please see a professional. The fact that you are worried is plenty of cause for you to seek medical attention. Good luck.

Meds and therapy: Mood stabilizers such as depakote or lithium to decrease the extreme intensity of mood swings, combined with therapy from a psychotherapist who specializes in bipolar disorder would be the most optimal approach. Don't medicate yourself. Ask for appropriate referrals for help that works for YOU.
