I cut too...I can relate to your story on lots of levels - school was difficult for me, too. I was always teased even among my friends. I didn't start cutting until college - but I started popping pills in middle school. Good luck with this monster...I know how tough it is to quit. It's the only thing about which I'm still uncertain about quitting - I feel confident in not drinking or smoking weed or doing coke ever again but I'm reluctant to give up my last "coping mechanism" to deal with pain.
Well done on getting into a school with which you're happy and to which you are excited to go! College is an exciting time and I hope you can "spread your wings" and really grow into yourself there. It's almost like getting a fresh start to be the person you've always wanted to and believed you could be (it was for me, at least)!
