Thesis statement for self-mutilation

It could be a lot of things.

Self-Mutilation is a rising issue in America. Three major issues about self-mutilation are that it is an addictive behaviour, scars are permanent, emotionally and physically, and it is a rising issue among teens.

You may want to reWord it some though. I'm only a 10th grader. Ha ha.
