I can definitely relate to all of this. SI does help alleviate stress and negative feelings, almost like, well, being reborn in a manner of speaking, because everything else disappears, and it feels great to hurt myself and be in control like that. Although it is bad, I do feel a sense of accomplishment the worse I SI, and like others here, the cuts and burns have become increasingly worse for me, too.
Ultimately, it is a bad habit and I am working to stop it. My counselor suggested a colouring book – she bought me an insect colouring book to doodle and draw in when I have SI thoughts.
We can beat this!
