I think self harm does a lot more psychological damage than you realise at first. You are feeling unable to cope and out of control and the feelings from self harm provide some temporary relief. They make you feel somewhat in control and ok for a while. At the same time you are developing a lot of angry that you are directing towards yourself. For me it becomes a cycle. I don't want to say an addiction, because I feel it is more like self punishment than an escape. I have never felt good after it. Sometimes numb or sometime less depressed, but I have never felt like it was a good thing. When I do it it become a vicious cycle. I get overwhelmed by something happening, and then I do it. I blame myself for whatever and feel like I have to. Then I feel ashamed of it, which makes me want to do it more. The whole time I like myself less and less until eventually I don't even think of me as me, but as someone I hate. I don't think be well and self harming is possible. I think it is too damaging. At least for me it is that way. It does different things for different people. For me self harming is a sign that things are getting well beyond my ability to cope.
