Welcome to the forum!
And I'm sorry your going through this, you're definantly not alone in this!

Do you have a therapist and/or psychdoc?
Are you on meds, and in therapy for ADHD/ADD?
In my expeirence the right dose of ADHD med has pretty much been a miracle drug for me. and my "bad" were actually all impulses, i did it before i thought. So the med stops that impulse, and lets me think clearly. But this definantly isn't the only solution, and could be diffrent for anyone else.
