The best thing to do is stop. It is hard, believe me but if they do find out then you can say that you have already stopped. In my case my parents never found out, but I stopped on my own.
I self harm, well im recovering, my advice is to tell someone if not your mom, someone to help you through, because I didn't and I had to get through it all alone and that made it a lot harder (and if you ask the doctor nt to tell im sure he wont).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
