The NY Times ran an article in September (9th?) featuring Cognitive Behavioral Therapy (CBT) as the only known cure for hypochondria. CBT changed my life for the better and I sound like a broken record here sometimes recommending it to almost everyone. The best thing about CBT is that it often cures depression and panic disorder in as few as 12-weeks! I urge you to look into it further. My two favorite books on the subject are "Been there, Done That? Do This!" and "Feeling Good" The former is a quick read and probably the best starter book on CBT but Feeling Good goes into more depth and isa valuable resource.
Check one or both of them out and give CBT a try; I think you'll be glad you did.
Don't expect anyone to help you, if you won't help yourself!
