You can not expect others to understand self-harm. It is something I would not understand either if I did not do it myself. I was shocked at the cashier at the food store this weekend. She was wearing short sleaves and it seriously looked like she use to cut deep and wide. White scaring and pinkish scaring. Her arms looked horrific and she was proudly displaying them. Even though I use to self harm I was still uncomfortable see that. I am thankful I never cut like that.
