Rehab has several parts. You will meet with individual counselors and also attend group therapy. The group therapy sessions and the 12 steps meeting, that you will be introduced to, will be an important part of your support system. Developing and using a support system is crucial, especially in the early years of recovery. These will be the people that can help you stay clean and sober when you are faced with trying situations in your life. This is something that you will have to work at and will not happen without effort. It happens one day at a time as you go through the program.
