I used to cut. And I just want to get this out there. By talking about it on here, all you'll get is sympathetic comments. I know it's hard to go or help, but you really have to. I did, unfortunately I got sent away. But afterward, I got a therapist, got to meet people who were recovering as well. It's hard to take that first step. But sometimes you have to jump, and deal with the rest accordingly. I was scared how my family would react, and it's ok. They're reactions will haunt me. And it's their feelings that made me want to move on. Because I knew they loved me. There is nothing wrong with you for doing what you're doing. But it hurts your emotional health even more to worry about hiding it.
It will be rough, but I garuntee it will get better.
A website that helped me was
Samaritans.org
You can call, email, or send letters. It's all anonymous, so I got to let it all put without worry. And after a few months, I got the courage to talk to my guidance counseler, and you should too. It will all be worth it in the end.
I guess that's all, but I wish you all the best<3
