There's a lot of reasons.

I read a book once. A boy's stepfather had committed suicide, and the boy was suffering really bad from... memories. It turns out that he had been abused. So he cut himself. He wore long-sleeved shirts, no matter the season, and the cuts were all the way up BOTH arms and across his chest.
