Sorry. I didn't see the post about ages down below when I posted this. I'm in my 40's. Started when I was about 20. Feel like I'm a professional who should have more sense not to do such a thing. But it still happens, and rather frequently lately. I cut my arms, stomach, and legs. When I was younger, I used to bruise myself, but that took too much work. No one know except my therapist. But she doesn't ask about it often, so I don't tell her how frequently I struggle with it. I feel too old to be doing such a thing.
