I'm afraid I don't have anything constructive to add here but I just read through the whole thread and my heart is going out to you Kev! I'm so sorry you're dealing with this. One thing that I did think of, and it may not be an issue anymore but if it is, ask to talk to a nurse instead of the receptionist. They're too busy doing the front office busy work most of the time that they don't have time to deal with the actual problems patients might have. I bypass the receptionist whenever possible at any doctor's office, regardless of the specialty, unless I'm just setting an appointment.

And it certainly sounds to me like you could be having petit mal seizures. My nephew gets those occasionally and he does the same thing - just staring off into nothing. Completely zoned.

Good luck!
