There are therapists that have experience in working with clients who come from high mind-control backgrounds. I can completely relate to the whole "evil" thing, and the nightmares. For me the word was "horrid" less damning than evil, I'll admit, but pretty tough to bear a life of. This type of self-image is one that just doesn't go away without the help of a professional-particularly when recovery is juxtaposed against a background of subtle, well-developed, constant mind-control that shaped us into knowing that we are really evil (and don't measure up). The WTBTS is a text-book example of how to inculcate blind allegience to a cult. They are expert at it. It may take an expert to heal some people from that.
It takes awhile to "train" a therapist in what it is like being JW. Most people need to be trained in the subtleties of the control, and are shocked by the reality of all the unwritten rules we had to follow. Not many are lucky enough to find an exJW therapist in their neighborhood (like I was)-but that does not mean that a therapist can't become educated. There are links to support groups and therapists at www.freeminds.org that could lead you to referrals in your area.
I tried antidepressants (they worked while I took them), but nothing took the place of really coming to an honest belief (with actual evidence) that I was not horrid, and finding tools for countering the times when the struggle returns. Antidepressants are appropriate to survive rough patches, but if it is the fallout from being a JW that is the ultimate root of a significant portion of the depression, then you will eventually have to confront that with some psychotherapy. It really can work. But it won't be overnight.
