Red Cross Blood Donation

So I donated blood to the red cross today.... I'm O-negative so I can donate to anyone. It stung at first but then it just burned a little then when they took the needle out it stung, a lot. But long story short I'm really freakin' dizzy and this has led me to wonder if the red cross is secretly full of vampires!!! Not really..... -.- Whatever.... It's still bleeding but I got Cheeseits, Oreos, apple juice, and a bottle of water. They told me to drink a lot of fluids..... so will do.
