There is always a chance for relapse after treatment, but relapses do not mean an end to your sober journey. However, there may need to be a readjustment of treatment to ensure the future success of your recovery journey.  It is important to be kind to yourself and maintain a state of realistic optimism in recovery. Relapse (not just in addiction but in depression, anxiety, etc.) is very common and having the right support system in place can make all the difference.
