Cognitive Therapy?

My new Doctor suggested I get cognitive therapy for my pain. I have been doing research and frankly, I don't see how it's any different from what I have been doing for YEARS. How is this going to be any different. All the positive thinking in the world is not going to make the pain any better or enjoyable.
SO, anyone have any information about cognitive therapy? So far it just sounds like the BS a few people I know subscribe to. It sounds very similar to what one of them told me... "You are in pain because you don't love yourself enough and it's coming out in a physical pain." WTF???
No, I have physical pain because I have liver disease, an enlarged liver, duodenitis, gastritis and tears in my stomach. It's not all "in my head". And happy thoughts and cute bunnies won't make eating less painful. I think positive a lot... I was called dellusional because it. I can hyperfocus on something else to keep my mind off the pain for a little bit. But when it's so intense that I am doubling over and in tears, happy thoughts and candy rainbows aren't going to make it easier for me.
SO, I want to know how this is supposed to help me. How it's different from what I do every day anyway. To me it sounds a lot like the "it's all in your head" crap.



Cognitive behaviour therapy actually isn\'t a load of crap in many cases. However, in the case of physical pain I don\'t see how it would help.
