I recently started to, I have done it a couple of times. Me and my friend did it once but we were 100% joking around, stupid, won't ever do that again ( don't worry we didn't bleed or anything) but over the last couple weeks, I did it again once or twice, because it's a distraction from depression and it's just calming to see the blood. I don't do anything serious. I only cut my fingers, and I only bleed a very little bit. It's not dangerous. Is this so bad? What's that bad about it if it's only a little bit, and it comforts me?
