Mike: I suffer from this as well! I just started reading a book called, "It's NOT all in your head! How worrying about your health could be making you sick--and what you can do about it"
Author: Gordon J.G. Asmundson and Steven Taylor
So far--it's right on the money for me! It's easy to read---I took it out from my library first before I buy it b/c I wanted to make sure it was what I wanted---and i am going to purchase it---either Amazon.com or my local bookstore!
You should check this out---and also contact your doctor about what you are experiencing! I am seeing a therapist (MSW) currently about this---but, I am going to ask my doctor to refer me to a therapist that has experience with Cognitive Behavioral therapy---b/c I need to change my thoughts about things (health, dying, etc...) before they consume me---and this therapist I currently see doesn't really do that for me!
Hang in there---and go get the book! go to your library----or call them! Hope this helps a little--and hang in there! I know how you feel--and you aren't alone!
