My friend have self-harm scar . My friend has a self-harm scar on the back of her right palm, I was surprised because we haven't seen each other for 2 years, I thought it was just a pen drawing but when I looked at her depression medication I can guess that he self-harmed, how to treat old scars, I have scars from an accident so I don't know how to get rid of them, my friend has a self-harm scar on his arm too (I can't bear to see it)
