My situation was very different. Therapy had become like an addiction for me. I had had 20 years with different therapists almost continuously, 55 years on and off on and off since I had an eating disorder as a teenager.

Withdrawal was tough but support groups have helped. In particular, for family-related complex stress have you looked into Adult Children of Alcoholics and Dysfunctional Families? They started out as just Adult Children of Alcoholics so some groups are still pretty much focused that way, and didn't seem a good fit for me. But I recently found a group that is pretty inclusive of the children of dysfunctional families, too.
