How should i tell my husband i cut to releive stress? i want to get help & stop but i can't without him finding out so tell him first?

Self-cutting: I'm not sure what your relationship with your husband is like -- i hope it's supportive. If so, please just tell him you've been in pain and have been using this method which you know is not healthy for you -- and you want to get help. It's not something you can just stop on your own. You need a therapist to work with. If you & he aren't getting along, include someone else you trust in the talk.
