Katelyn, I don't think it is easy for a parent to hear their child is self-harming. What do you hope to get by telling them? I am not saying you should not confide in them, especially if it will help you stop, but what are they able to hear. Some parents hear stuff like that and want to take you to the emergency room.

One way is to slowly let them in on your frustrations in school. Maybe they already know about the self-harm and don't know how to deal with it. I think the easiest thing would be if you stop self harming then tell them you are working on this problem. Do you think your parents could hear that and not go into a panic?

What help are you getting from a pdoc or therapist?

Maybe that is the way to approach it, talk about problems in general without talking specifically about self harm with the intention of getting their help with therapy or medicines. Of course if you are over 18 you can do that on your own.

The body is our friend one of my teachers used to say. Don't do anything to harm it or we may lose that friendship.
