Could you talk to a school counselor? Why do you think you would have to skip school for a week? I wonder if you are assuming inpatient treatment. I sincerely doubt that inpatient treatment would be warranted for someone who has enough of a sense of responsibility to be concerned about missing school. That tells me that you are most likely able to be trusted. Also, you don't know that you necessarily cut yourself. It's fairly common for people to get scratches and stuff and not remember. I'm not saying you didn't, but just that maybe you didn't.

It sounds like you have a lot going for you, and that you are bright and responsible, but also hurting a lot. You definitely deserve to feel better and be safe. I know it's scary, but I hope you do talk to someone. If you have a friend or someone you can trust, maybe you can ask them to go with you in case you start to panic. You deserve to feel better.
