As far as thoughts vs feelings the thoughts always precede the feelings. They might even be subconscious but it's a process of negative cognition that makes you feel sick to your stomach etc. If you want to fix anxiety without talking about the thoughts you're going to have to use drugs....the very basis of cbt which is the therapy that works for anxiety is dealing with the underlying thoughts and you really need to tell a T about it because it's nearly impossible to do yourself. How do you know you're thinking about something wrong if thats how you've thought your whole life and perhaps how everyone in your family has thought too.
