Spending a year at death's door did wonders for my neurotic crap. Not something I really recommend. But I would recommend you watch the movie "Beyond Rangoon" and then go do some volunteer work at, say, a homeless shelter or working with the chronically ill or something -- something that really punches your buttons and gives you a bit of perspective. Or at least join some email lists for people with chronic, incurable illness.

Also, do some research and consider vitamin therapy. There may be a brain chemistry issue that may be very treatable with aggressive nutrition.

Best of luck.
