I know exactly what you mean. I haven't done it in quite awhile, but when I do I have to hide it with wrap around leather bracelets, etc.
But I have been feeling so out of control and angry lately that I think about it all the time. I have also reconnected with someone I spent time with years ago who I basically had to explain my therapy and depression to, which was a miserable experience, as he can be a bit difficult anyway...plus he is more jaded since he went through an awful marriage/terrible marriage therapy since we last hung out. So I don't think he would react well to seeing cuts..so I do think about it like you do..but then I think, I could try somewhere new, should I, is it worth it? I don't even know.
I feel your struggle and pain though. Of course I will tell you to hang in there as long as you can...I guess that's the path I am on myself. You can always PM me if you ever need extra support
