That sounds alot like how I was in my late teens before I got really sick. I had anxiety from all sorts of important things, and could´t sleep the night before something important. I also got gastric catarrh, when I had an strong anxiety period, and couldt eat anything!
But I feel that I was still alive then, now I newer have a free mind, and feel well.
But you use the other methods than ERP of CBT, because you dont have ocd, although you get stuck in thoughts and thats obsessive thinking.
It was ERP I was referring to when I so clumsy said `the real cbt` sorry for that, I wasnt aware of the different forms of cbt.
