Hi hotas-
your posts here are good and very illustrative. It sounds like you are really hurting and and sometimes it is hard to see the forrest for the treees when we are feeling so rotten. Cbt is nothing like positive thinking though they seem similar on the surface. Cbt is based on finding the thinking "errors" you are making and countering them with "objective" thoughts. You said your thoughts are not the problem but I see several of the thinking errors that cbt is based on being made in your notes. Jumping to conclusions, blowing things out of proportion and extreme thinking seem to be your main offenders based on these posts.
You jumped to the conclusion that simply reading the obitz book would cure you and then blew things out of proportion when it didn't. Even obitz said he thought cbt was a joke and wouldn't work for him when he was introduced to cbt, so you sound just like him and he is presumably better now. I am a big fan of cbt groups and think purple is right that getting involved with one may help jumpstart you into the process. Don't expect to learn many more exercises than the ones outlined in the obitz book though as all cbt exercises are variations of the tea form and the putting things back into perspective exercises that are outlined in the obitz book. Cbt appears to be too simplisitic to work, but in my experience it does and I have seen it work for too many others now not to be sold on it. Like my group leader told us and I always say.... The more effort you put into cbt the more you get out of it. It's basically up to you to how much you get out of it which can really build your confidence and self-esteem. I hope you give it a try because I do think you can be helped a great deal by it if you work at it. It's hard as hell at first but it gets easier the more you practice using the tools.
You also said that there is nothing in the book on getting over your past. Why would there be since that is exactly what cbt is about learning skills to go forward. Our group leader would cut-off anyone who started trying to talk about their past and say "i don't care what caused your problems we can't change what's already happened. I'm here to teach you how to fix the thinking patterns that were caused by your past so you can live anxiety free in the future."
sorry this ran on so long

I like purple and haley's advice and I hope you give the tools a whirl. I think you'll be glad you did :d
good luck!
