I don't think it's self-harm. Cause I'm not a cutter. I never got up the courage to do so. Hold a penknife across my wrist many times in the deep night and I have only make the tiniest cuts ever. I used to hit the wall with my head. Nothing serious. No blood. I enjoy the throbbing headache that makes me weak and I have to lie down. Still, I don't think its self-harm cause I have got nothing to show. No one will believe me. That I'm hurt.
