I cut sometimes, I used to scratch when I was younger, when I get extremely overwhelmed I head bang or hit myself in the head. I've attempted to take off limbs but cutting off circulation before. I also further my cutting by not doing anything to keep my blades sanitary or clean my cuts before and after. I don't cut often, maybe once every month or two, and I prefer to be inconspicuous about it god forbid someone question me, so I usually just do one deep cut in a random part of my body.
