Do you donate your blood?

I do not like needles, but I do donate blood when I can. Although for some reason, when I donate blood, my body doesn't like me so much afterwards. The drastic drop in blood sugar really gets me, and usually while I am still hooked up to the needle. So I have a hard time doing it. But the last time I donated blood, it was well worth it, because it was for one of my own children.

I'm probably going to sound horrible, but I never donate blood and I will probably never bring myself to be able to do it either. I am a huge needle chicken. I get sick to my stomach at the sight of people giving blood. I get lightheaded and all nerdy panicky if I have to get my blood taken at the doctor's office. I guess I'll have to leave blood donation to other people braver than me.
