Help with Anxiety Attack Self-Harm

It sounds a lot like my breakdowns. Mine have been happening for maybe 5+ years now? I don't have a name for it, I'm sorry, but I can give some advice. Mine slowed a bit with proper medication. Meds might not be for you, and that's totally okay, it's not hopeless if you don't want/can't handle meds. I established boundaries with my family: crowding me made it worse, it was better to let me handle it by myself. I also took time to figure out what made me feel safe: a quiet, private room, with a heavy blanket wrapped around me, or certain comfort items that made me feel protected. These are just examples, and there's a good chance you'll experience things much differently than I do, but in my experience, if you don't put yourself in a safe space during the breakdowns, it is so much worse.
