Dependence on someone who has helped us out of a rough spot is natural. Part of the behavioral program should focus on learning new coping skills and letting go of that attachment.
Incorporating new coping skills and using them on a daily basis takes time. Often this process goes beyond what third party payers will reimburse. You still have several options.
You can request an extension of coverage of services. Your physician and therapist will probably have to write letters of justification. A relapse plan may be required. If your coverage is extended, then the remaining sessions should focus on preventing recurrence of symptoms.
This can be done several ways. A daily journal, diary, log, or blog can help you. Self-monitoring in this way will guide your daily coping, relaxation, and distraction practices. Practice positive self-statements. Practice coping skills and think about the new ways you've learned to solve problems.
Pay attention to areas where daily life events and stressors affect your pain and function. Applying all your new skills consistently everyday may help offset some of these added bumps in the road.
The cost of ongoing professional help may be more than you can afford. If your insurance carrier doesn't approve additional treatment, perhaps paying out-of-pocket for one or two relapse-prevention sessions would be worth it for you.
