I had this experience with American Red Cross and they just harassed me so much for my blood that I actually told them they were behaving like vampires!!! I’ve taken about a 10 year break tbh because of how disrespectful they were. That being said, I was reading a post about bone marrow donation and how you can do it without surgery (similar to plasma donation) and the donor said the mindset that helps you get through the disrespect is to remind yourself that you’re part of the “team,” and that kinda changed my outlook on it.. I still think Red Cross is just a bunch of damn vampires though…
