Scratching myself with sharp tweezers?

[Jasmine Dhar]

this year I have been feeling depressed and sad and lonely and even though Im in a pretty great place, I just want better and I feel like some of my old friends are deserting me and not many people legitimately care about me. I felt really down a few weeks ago and scratched my left arm and left a bunch of red/white marks. all but one faded away. I didn't bleed. it just kind of helped relieve the stress.
Today, I felt bad and I remembered what I had done before and even though I know I shouldn't have, I got my sharp tweezers and dug them into my arm/dragged them down my arm making harder deeper marks, I didn't bleed but I know if I had pressed a little harder I would have. its this sort of prickly, stinging sensation and I feel better now but I dont know what I should do. is this bad? or am I just being stupid??
