I want to suck your blood!

I realized the my blood type is rare, if not the rarest blood type out there.  AB neg.  Kinda cool.  I made a comment to my husband that I need to go donate blood, and he said, no way, it's rare, you need what you got!  Okay, it made me laugh, but I guess you had to have been there.  Anyway, I have never given blood.  The one time I tried to, I was underweight (ahh, high school).  I know I meet the weight requirement now, and I'm pretty sure I meet all the other requirements as well.  So, why don't I just go give blood?  Well, to be honest I'm not sure where to go.   Also, I'm not scared of needles, but I am scared that I might have some freakish reaction and passout.  Ugh.  So don't want to do that.  Hopefully, within the years I am here on this planet I will muster up the courage to go give blood.  I'm sure someone out there could use it.
