Can any doc tell me what's so wrong with self-harm?

U can hurt yourself.: There are many ways of harming yourself ; usually they can be dangerous. Some people don't take their required meds like blood pressure pills or insulin. Some drink too much ; may get cirrhosis. Some smoke too much ; may get lung disease or illnesses in other organs. Some cut, hit, punch or burn themselves. I don't think I have to tell u that these actions can be harmful if they are severe.
