Hi there, I just wanted to reply to this because I been where you're. I was like 6-9 months of self harm free then messed up during a stressed out day. The important thing to remember here is that you're not worthless, we all make mistakes. Relapse is an important part to recovery, without it recovery wouldn't be achieved. All you can do now is pick yourself up, and get back to recovery. Remember you're stronger than this addiction, and use techniques that you know help you. There's a list of techniques that users have used to help with self harm in this section so I'd suggest checking that out. You're not useless and it's not four months down the drain. Four months is a big success now let's get back to it and aim for many more
