I think a therapist would help a lot to.

Sometimes part of the problem is not being able to comprehend stability if you've had constant depressive episodes for a long period of time. Therapists can also help you understand your anxiety and help you work through it so you can manage it better and not have to rely on medication as much. (Esp if they are PRNs)

It's not an easy path though, and often therapy is very difficult before it becomes easier.
