Then get help. Somehow.
At this point, if you tell your parents that, they will probably be more than willing to get you help because you are admitting that your behavior is *unacceptable*, even to you.
The fact that you know that this isn't "working" for you speaks volumes. I agree that you need help in person--more than anyone on this forum can offer, though we will still be here for you as much as possible.
Take care, and let us know what happens. You are not a bad person. Don't ever think you are.
