I've been dx with psychosis and I also si during my psychotic episodes. Mostly in response to the voices.....the last time I self harmed was last week....but like newtus mine are superficial and nothing as severe as needing stitches let alone surgery.
I self harmed all the time during my last psychotic break which happened over the course of two months. My arms have plenty of scars. But I don't just cut. I strangle myself too and bruise myself too.
It's such a bad habit I hate it so much! But I don't know what else to do.... There are other alternatives like drawing in yourself where u would normal consider cutting. Or holding ice. But none of then give me the same satisfaction as cutting or strangling.
