You're just about to re-enter society after a lengthy stay in rehab. You fell into anxious thoughts when you try to speculate how your life will be now.
You know you could relapse despite your desire to stay clean. There are a few things you can do to help you keep away from alcohol and drugs.
Rehab is not a quick fix because recovery takes time. Seeking and remaining dedicated to the aftercare therapy is one of the best options for you to remain clean. Developing support systems and communicating with family are important in your journey. Since you can't make sure to remain sober with a single advice, you should use what you were taught in rehab, which in addition to a combination of tips can provide you with useful tools for a good life.
When it comes to recovery, using the method that has worked for you before will work for you again.
