GAD (generalized anxiety disorder) question?

I know what you mean. I have anxiety with ANY caffeine I drink now. I cant even have the smallest piece of chocolate without my anxiety going out of control and heart racing etc. I'm told it is a BIG contributer to anxiety. If you stop caffeine (I know its hard) all together then your symptoms should improve. What do you take for GAD? The dr says I dont have depression or anything so the most she would prescribe me is a beta blocker and sleep medication but nothing else.
