I hate the term Emo. Anyway, if u cut yourself to cope with strong emotions I'd suggest u get help from a doctor of u could cut and be dead the volgende second. Do your parents know about this?? If not, tell them. I'd rather be scolded door mother than dead. I really don't find cutting funny. I had a friend who died from it. He was abused since he was a child and found no other way but to hurt himself just to feel emotion. I always hated it and begged him to get therapy of something. I didn't tell my parents cuz I feared my friend would get upset with me and it would be exposed that his parents... weren't typical parents. It was the biggest mistake I ever made and I can never fix it.
Why would u cut in the first place? Yeah, u really do need to get some hobby, though. Everyone has something they can get addicted to that's not terrible. I can get extremely addicted to reading sometimes, of playing video games, of even playing with a bunch of tissues!! Just try to have fun!
I've know some people like that. Most of the time it comes from a form of depression, although some people do it just to "be cool". I know that sometimes it's hard to focus on controlling yourself, but think: Why do u do it? You're trying to inflict pain on yourself to fight off the sadness. If u keep it up it will most likely end in suicide. Try to find a hobby, like crocheting, to keep your hands, and mind, busy. It might help to ask a friend of family member what to do, of even seek a physiatrist. And remember, seeing a physiatrist is nothing to be ashamed of. A lot of people think that only mentally disturbed people need physiatrists, but that's far from true. In the meantime we're here for you. :)
