When are you experiencing the anger/agitation? Is it during or outside of episodes?

When I increased my lamotrigine, my natural anger and agitation subsided. The increase even helped, to a degree, lessen the agitation I get during episodes. However, that's just my experience.

You should ask your psychiatrist if adjusting your antipsychotic and/or lamotrigine could help you.

As far as cutting goes, do you go to therapy? A therapist could help you learn techniques to find healthy ways to channel your feelings toward something healthy. Good luck!
