I am hurting inside...

Okay...My friends and family don't know this,but I cut myself when I am stressed out or angry over someone or something. At first it was just for fun,but when I was really angry I felt great after cutting myself.It's like I could feel the pain from the inside.It really hurts and I had to do it. When I quarrel with my friends over something I did,I hurt myself.When I accidentally did something wrong,I cut myself.It has finally evolved to a stage where I cut myself over the slightest things. It's such a painful thing mentally.But physically, it's gratifying. and being different in terms of sexuality does not help ONE BIT. Ugh,frustrating...
