You'll be ok. Once whatever you have been on leaves your system just focus on finding who you are and goals in your life. I'm not going to say the group sessions or counselors are going to help, but focus on you and don't make excuses. I'm a huge alcoholic I've been to rehab before too. Most people in there don't give a shit. Take the time to figure your self out. Pretend it's a vacation. It sucks but at the same time it doesn't suck. Figure that out and I promise you will have a fighting chance. Good luck.
