I donated blood today and oh man I feel like passing out

So our school has this thing where a bunch of medical staff come in and take over half of our gym and kids can donate a pint of blood. Well, I thought I could do it. So I gave blood and the entire time I had my ipod on blaring Jeffree Star because I had to focus on something and he's so funny. When I finally finsihed I went to stand up and almost passed out. I was in there at 1:30 and didn't leave till about 2:20 because I was so dizzy.

I actually still feel naseaus and a little dizzy and extremely tired. and it's 3:30. Man. I am so tired. lol

Anyways, my point is, if you're terrified of needles(which I am) and you're a small person. Don't donate blood.
