17 is an overwhelming age to be for pretty much everyone! Have you told your parents that you feel like they hate you? Have you talked to your parents about your thoughts right now? It might be easier if you print off this post and show it to them, they need to know how much you are struggling, you might be surprised by their response.

Parents don't know everything and parents make mistakes, but they need to know what is going on with you to be able to support you. And I agree with Lee, is going to therapy more frequently an option?

Please don't hurt yourself. The relief it provides is temporary and the problems are still there, unresolved. Eventually, you will regret it..I have scars from more than 20 years ago that I wish I didn't. It's a terrible road to travel on..I think boxing sounds like an excellent outlet for you. What would it take to get you in the habit of going to the gym again? Sometimes, when everything in us is screaming I just want to go back to bed and not deal with this - that is the best time to take action. Actively force yourself to go against those negative thoughts and with time it may become easier.
