Orange, thank you for sharing this and your honest vulnerability. I will offer my take:
I too had a spell where I fainted a lot. Like, every time I got up from my desk I was on the floor. Eventually spent three weeks in intensive care with no front teeth, a broken nose, four broken ribs, a brain injury and a ruptured septum
Finally had a doctor that asked WTF? Heart monitor for a month and turns out I have insanely low blood pressure. Who has LOW blood pressure?
Turns out I have a condition called orthostatic hypotension. I take a pill every day to raise my blood pressure and it has not happened in 18 months. Got my teeth fixed.
Funny, but my Dr. says, "hey dude you can have more salt on those fries if you want..."
Sorry to over share, but man I wish I had heard of the condition before I passed out 20 times
