May I suggest a book to you. Actually, I cannot take credit for it...PMartin, who is a poster on this board, brought it to my attention. It is called, "The Divided Mind: The Epidemic of Mindbody Disorders." It is by Dr. John Sarno.
I am only in the beginning of the book, but I find it fascinating and almost can't put it down. It can get rather technical, but if you stay with it, I think you will find it very informative.
It may give you hope that the body DOES have the ability to heal itself. Remember, attitude/emotions and your outlook on life, are the biggest part of the journey.
