He is a cutter. he says that he isn't trying to harm himself. I trust him, but it really hurts me to watch him do this. He says it's just a means of release, but his family thinks otherwise. What do I say to him?

I want to get a plot of tilled and possibly enchanted soil in a cave or underground. It was have to have some kind of natural light source.
