Welcome and it is great to have support ftf support. So start going to meetings they won't hurt. Percocet will have physical withdrawl symptoms like heroin, I don't know hiw much you take and my suggestion is go to a detox and that will help with a safe structure for withdrawl, and possibly some help with the withdrawls.
Seeing a substanc eabuse counselor will be helpful for your journey and go to meetings will enhance your life ten-fold! When I started my journey into sobriety I went to 12 step meetings and also seen a counselor, this helped me alot. Be careful with yourself don't mess around with this on your own, you seem ready to take some action or you wouldn't have typed here, way to go!
Good luck and keep posting!!!!
