I'm not allowed to give blood 'cause of the meds I'm on.
Ditto for me because of chemo, cancer, and the ongoing anti-cancer meds. I get mixed reports on whether I'll ever be able to donate blood or organs. Some say that some groups will take them, but I can't even think about it until I've been off the meds for five years.
Big bummer, because I'm O- and used to donate all the time.
Last time I saw a blood mobile I went in and thanked everyone, telling them a little of my story. I needed 6 units at various times during my treatment, because I was so very, very depleted. I told them people like them saved my life and everyone got all weepy and gave me a t-shirt.
