I fidget a lot, so I pick my scabs, when I get them, small bumps on my skin, and cuticles; many's the time I've made my cuticles bleed, but like Bumblebee stated, I'd consider the issue more of an impulse control thing than premeditated self harm, though I still file it under "self harm". I'm not sure if it's conscious relief I feel from doing it, just because it's something I'll catch myself doing absentmindedly when I'm nervous or restless, but I think the stinging pain still manages to become something I feel like I deserve, and then the impulsive picking feels justified... if I'm making any sense? Idk, maybe it's a self-esteem thing. Or all of the above.
