Big congratulations Acadia. I know what it's like to have an undiagnosed condition. I would just appear to switch off for up to 30 mins at a time for a few years, then my doctor sent me for tests & it was found that i suffer from a mild form of epilepsy. My initial reaction was OMG - epilepsy, but then 5 mins later, it was "ok I know what's wrong, what to do, i can get on with my life & not worry".
