The first step is to walk out of the room where 당신 keep your blades whenever 당신 feel that addiction coming on. If 당신 can, get rid of them unless they're needed for other purposes.
Then I'd say, if 당신 feel like 당신 want to take that step, talk to a friend, counseler, parent/guardian, anyone close to 당신 whom 당신 trust.
If 당신 don't feel ready for that step, call a help hotline and talk to somebody there.
If 당신 don't feel ready for any of those steps, 당신 can always send me a message and talk to me 또는 my friend (her 아이디 is ComicLover13) about whatever is bothering you. We do this often for people on the site and in real life. don't feel awkward when 당신 do it as Sometimes it just helps to let it out.
Anyway 당신 go about it, just try and find some help in anyway 당신 know how.
I've been through this situation. Luckily, I figured my way out of it. I'm just trying to prevent someone from making a bad decision in their lives. And sometimes, 당신 just have to be a little harsh to get your point through.
