CathrynRose,
Hypochondria is in the spectrum of anxiety disorders, so you may want to start there. Hypochondria is the result of whatever anxiety you are suffering; however; hypochondria has a little *twist* to it that involves a component of obsessive/compulsive behavior. For example, the real NEED to look up symptoms on the internet or in a book is a form of compulsive behavior one does to try to ameliorate the stress over the perceived threat. It's no different than those wacky people we laugh at who wash their hands 40 times before they leave the house because they are afraid of germs.
So, with that, hypochondria is a bit harder to treat that your garden variety anxiety.
I will TOTALLY agree with Jennasis in that I think hypochondria has a very low cure rate with therapy. I won't even tell you the amount of money I have spent and people I've visited who have been unable to even TOUCH the worries.
Some of my better days with this beast are when everything (and I mean everything) is going well in my life. Right now, with a teen and a pre-teen, a hellish commute, and a job that I don't like, my hypochondria is in overdrive. Then, when I get "real" health problems it is so much more magnified.
But I have had times were all was well with the world and my hypochondria has actually been non-existant.
