I was raised in the TRUTH, and I escaped at 15. I think I was traumatised for a solid 10 years afterwards, but it probably didn't help that I was trying to make it on my own so young. What helped me a lot (finally) was reading about post-traumatic stress disorder. (If you're interested, tell me and I will list the books I read.) At least then I understood my symptoms a bit better. I also discovered Bach Flower Remedies, they are homeopathic and they helped me with things like the Sunday gloom and doom feelings. They might be worth looking into if you like alternative type things.
I think, if it's possible, that forgetting the whole thing for a while and trying to have some fun is the best healer. Travel is also good, if your phobias and bankbook permit it. Travel makes you realise what a tiny, irrelevant world JWs live in. Oh, and don't watch or read the news for a while. It's always dreadful and I think it triggers the old beliefs about what an awful place the world is and the old fears of imminent apocalypse.
