Mind as well join the conversation.
I don't care what people do. As long as they aren't annoying or angering me, I'll let them do whatever the fuck they want.
I've been cutting for one and a half years. My best friend has been cutting for just about the same amount of time. The funny thing is, the only reason I befriended her was because she knew what was going on (afterward I found out that she's one kickass person, but that's besides the fact).
I definitely get worried about her, as she worries about me. But we trust each other.
I am in no way saying it's good to stay quiet about this. I would just talk to them. If they want to go tell someone, they can. That's an extremely good thing to do.
I didn't know why I was doing it at first too, but then I too started getting addicted to it. I've seen a psychologist 2-3 times, because people have found out about it and told her. I wouldn't have went there by my own will. That bitch tells every teacher in the school about it. Student-psychologist confidentiality my ass. Anyways, sometimes it's better to reflect on it yourself, think about why, how it makes you feel and if your ready to stop. Then, if needed, it's good to go to a psychologist to figure some things out. It's also good to join online communities for self injury and eating disorders, the like. RecoverYouLife.com is a good one.
Cutting can fuck up your life. There will be scars, and it's nothing someone should get into. But it's almost unavoidable if you have depression, stress or anxiety issues, body dis-morphia disorder, bipolar or any other mental illness. It also comes from an inability to communicate with someone well enough, a feeling of being trapped in your own mind. It's not pleasant.
My self injury has been getting a lot better, as I've taken up creative writing. It's a far better outlet, but I'm not completely well yet.
If anyone has any questions about depression or self injury, or need to talk, just pm me.
