NH -- Yes, we've seen thousands of people recover. You will most likely recover quickly. In the worst case scenario that you take a long time, it will still get better and better an better during that whole time. Nobody, but nobody feels as bad as you're feeling for very long. You will start to have little windows, then the windows will get longer and more frequent.
Also, if you were to take a longish time to recover -- which I don' t think you will -- your relationship to the symptoms would change a lot. Right now, it's new and shocking, unfamiliar. With time, even the people who are feeling crappy discover that they are just feeling crappy. That's bad enough, but it's not the same fear that something drastic really is about to happen to your health. You learn that this is a *feeling*, not a fact. You learn coping strategies. You muddle through.
So, no matter what happens -- and I think you will start to recover very soon -- you will not feel this bad.
