As others said , Could be Borderline also, but again no doctor here.

Since your newly diagnosed Bp you probably need more time to find the correct medications that are going allow you to level off and find your baseline.

Do you have a Therapist? If not you should see someone, they will help you learn coping skills that will help you manage you life is a more healthy balanced way. I have a history of self harm. I have gone 2 years with out self harming, that is the longest I have ever gone.
