ITs a form of coping one picks up just the same as drinking or crying or anything else that works for the individul.

Is it wrong? It depends on who you are asking.

Health wise there could be problems such as infections or scars.

Socially there is the factor of being misunderstood and judged.

My little brother cuts and works in a fast food resturant with mandatory uniforms that do not cover his arms, this leads him to be heavily scruntinized and I would think it would be bad for buisness. If you think about it, it is not appealing to get food from someone who looks like thier arms went through a cheese grader.
