Happiness is a choice. Part of the deprogramming needs to be focused on how to change your outlook to positive.
Many people experience angst nowadays (in western culture). It has become a hallmark of the American landscape because of 9/11 and the way it has been handled. Negativity can be found anywhere if you look for it. It's better to see life in a positive light, and work towards changing the negative.
Do exJWs exhibit over-exaggerated qualities of angst? From reading this board, if that is a true barometer, I would say no more or less than the average person. It all depends on your locale and social set. If you live in Detroit, and are from a steelworker's family, well, you may be experiencing that feeling. And I can't blame you.
Read "The Catcher in the Rye" by J.D. Salinger. It's all about the subject, and many-layered, which is why it's such a famous novel. Education is a wonderful thing.
We, as a group, are generally a positive bunch. This would make a good 'local needs' talk, though! LOL! :P
