I know a very good mental health professional, a trained psychologist with a Ph.D. She says (and I'm paraphrasing) that 99% of people's problems can be treated by getting away from sources of stress, and exercising. These things work much better than most forms of therapy, and most of her sessions involve convincing clients to do these simple, effective things.

So if you're having problems, going to Thailand is excellent medicine, if you can afford it.
