Am I bipolar?

Are you on any kind of medication? Mood swings can be very common especially for younger people but the physically harming your self along with suicidal thoughts is not normal. Honestly if its to that point you could be very well bipolar and should seek some attention. You have to remember that everyone has conflict/issues in their lives, and physical harm to one's self isn't the right path to take. The pain you would inflict on your friends and family would be worse ten fold if something were to happen to you.
