Firstly, welcome to the forums shanice
Now, blood donors are required to be healthy in the first place, and all blood is thoroughly tested for diseases well before it makes it's way into anyone's veins. It's perfectly safe. My mother had a blood transfusion several years ago and she is still here today, caring for her family and living life because of it. Why would god want a mother of four to die and leave us behind?
The blood is safe so I don't understand this "ick, it's someone else's blood" nonsense. It's sheer ignorance on your part, shanice.
