Yes that is still considered self harm but there is help out there for it. It can happen at any age too, I know it can feel odd and isolating when you're older and people always say it's only teenagers who do it, but that's not true. Anyone can feel distress and thus hurt themselves to relieve and deal with it. I urge you to get help, start with your own doctor and go from there. No one deserves to go thrugh this you are worth so much more, I promise. Good luck.
