When I was in college they said I was too lightweight and had small veins, so instead volunteered w/Red Cross to set up chairs, take filled bags to containers, show people to seats and to canteen. Did that for quite a while and then my at-time-boyfriend <now husband> donated blood a couple of times - first time, was fine, second time had lots of trouble like you describe, Babyblue, and ever since then he has phobia about blood draws for routine workups. When he is medically required for bloodworks they have to use butterfly with him, too. And he can't watch. I can watch them do it on me, no problem. But am sorry that you had such difficulty!
