Fainted or maybe Sezuire from the head rush of standing?

I'm three years out form VGS and maintained my 170lbs weight loss for two currently I am 175lbs last month I had my yearly round of blood work meaning everything... well last Tuesday I was putting away things in the fridge when I felt that feeling like I had just got up from laying down... but this time it kept going... I turned around and tried to make it to a chair but couldn't my boyfriend was doing the dishes at the time so he was right next to me I said "I'm gonna faint" by the time he said "what?" I was on the ground completely unconscious with my eyes fixed blankly he said my leg was twitching during and my breathing was labored after about 10-15secs I finally came to... it felt like I had just had every ounce of energy zapped from my body I almost just had him bring me a pillow to lay on the floor but I managed to get up and get to the bed... immidetly after I broke out into the worst sweat of my life... it looked like someone had poured water on me... I had only been awake for an hour or two and then slept 10hrs after that episode... I was wondering if anyone had any ideas... I should have went to the ER but just didn't go.. (I know I'm getting an app this week)

Wow - get yourself to the nearest doctor ASAP!  Much of what you described sounds like a mild heart attack.  

Wow...it can be anything. Seizure from low blood sugar, stroke, heart....better check with a doc.
