I passed out!

I was at comcast today and I passed out! I was standing there for like 1/2 hr, then it got really hot. Next thing I know everything is going black. Someone carried me over to a chair. I got cold water and everything became clearer. I called the dr and she told me I needed to eat. I'm eating now but I still feel like crap. I can't believe I passed out, how embarrassing!
