Dizzy Spells? Near fainting, feeling like you just need to sit down/lay down?

I've been testing for every possible physical aspect, anemia, blood pressure, diabetes, etc.

I do eat, and my experience with these is that I've already eaten same day, so not that.

My primary, doesn't rule out MS on this. But most MSers that I know, don't usually get these.

Almost feels like a panic attack, without the heart palpitations---which I had a brief heart palpitation moment, yesterday.

Stress trigger, would be my stepmom is coming to visit today.

Just curious, if this, is anxiety over anything else? Haven't had one in a couple of months. Just had one...
