Hello.

To feel ok you need to understand what your anxiety is and how it effects you. Your doctor says you're fine and that's that. Your worries come from no place other than yourself. You constantly worry and because of that your nervous system is constantly on edge. Thats why your general anxiety can affect you at any time even when you don't have those thoughts. I'm short on time being at work but read around and learn what your anxiety is. You'll understand how to overcome it.
