If you are interested in CBT, there are many books on it. One that comes to mind is "feeling good", "the new mood therapy" by Dr. David Burns. You can find this book on Amazon really cheap. I bought one used for six dollars.
I hope that this helps some. Good to see you posting here Nana, I am usually on fibro forum too,.
I hope that you feel better soon, and I am sure some others will have some advice for you.
Hugs, Karen
