I can't say I totally know how you feel but I understand a little bit. I used only cut on my fingers because if I cut anywhere else I'd be caught, but now it's gotten worse. The first time I cut I said I'd never do it again but here I am. I gained some control over this by finding other things to do than cut: I squeeze an ice cube in my hand till it hurts so bad, I've also heard that snapping a rubberband on your worst helps though I've never tried that. Also try asking for different medications if the ones your on are not working. I'll be praying for you.
