I didnt feel anything

I was sitting on a bench outside in school and were were just talking. I sarted scratching my arm with a stick and it felt good. I ask him if he wanted to scratch my arm too bcs sticks arent that sharp just for fun and he aaid ya why not. He just scratched it a little and then stopped. Then i continued and scratch my arm harder and harder bcs i had some kind of urge to do that. He said stop and started throuwing sticks at me. But i didnt listen. I kept on scratching myself harder and harder. I wanted to see my blood so badly. Then i decided to try and scratch my arm as hard as possible. My friend said stop and was going to me anx tried to take the stick from me but i dodged bcs i felt like i had to do it. Then i pulled the stick up and hammered it intoo my arm. It was bleeding but it didnt hurt. I was confused bcs it actually felt good. My friend was shocked and slapped me XD. I realized then i had a problem hh.
