>>4227822well in my trip to a psych ward i learnt from some friends i made there its to release stress, like there will be sometimes when you are so fucking overwhelmingly depressed and stressed it will start to physically hurt, i've experienced it but never cut to relieve it, apparently it helps. but a lot of the time i reckon it was just for attention because edgy teens were like "uhhh we are all gonna die nothing matters"
