Cheating: my biggest catastrophe yet

I cheated on a test. No - I cheated on two tests. French and science. Yes - the biggest mistake of my life. Yes - you’d have thought I’d learn from it the first time. After being caught the second time this friday, I came home early, locked my room, and have basically been here ever since. Actually, there’s no lock on my door, so the only way prevent my parents from entering was unplug the huge old computer and put it in front of my door, along with all my shoe boxes, ect... I just need privacy sometimes. Its now Saturday afternoon, I’ve skipped a cross-country meet and this morning’s State Championships. I’m confused and don’t know what to do - a normal teenage feeling, right? Except for the fact that I want to go to a boarding school and never want to go back to my school. I mean, I’m fine with doing the work from home, I just can’t see how to physically go back to school. My parents are trying to help me, but its hard for them to help me when I barely communicate to them. Well, here’s my way of communicating: in my head. Not a great way, is it? Anyway, this is a running lists of thoughts and problems I don’t know how to tackle...

I don’t feel very moral anymore. It feels like I’ve destroyed my reputation.
I don’t feel accepted anymore (at GDS).
I don’t know how to deal with one problem at a time… To be happy, I need to deal with social stuff first… To deal with social stuff I need to be somewhat ok in school/academics, which brings on a whole new set of problems
I don’t know how to get through an entire year. It’d be one thing if I could start back on day zero.
With everything else I have to deal with, how do I deal with talking to Kate and Tom the day I get back?
How do I take the science test?
What do I say to people?
I can’t just go to school and not be sociable.
I’d like to invite Jake, 2 new girls and I guess another guy over next week-end for a sleep over.
I don’t know if I can make the commitment to running anymore. It’s not fair to Anthony when I just can’t show up some days, or to the team that’s counting on me. I’ve been thinking about just going to the work-out room after school and going on the bike or elliptical and study (there’s a place where I could put a book and study while I exercise… I work better while moving… I’m a kinetic learner).
I’ve so ruined my relationship with my teachers. They can say they’re looking past it, but how can they ever forget this? How can they ever think of me the same way?
My dad says I’m just running from my problems. Am I?
All I know is... I’ve built my self a slippery slope and somehow I need to get myself out. And fast.
