Banned

I've never been banned from anything before but today I got a letter saying I wasn't to give blood again.
Black-balled, barred, do not pass go, your names not the list so you aint getting in.
How dare they!
Just because of a teeny weeny little fainting incident. One fainting incident in 23 donations.
It was entirely my own fault, I've learnt my lesson, won't make the same mistake. I'll be careful. I've even given blood since and was absolutely fine.
I was one donation shy of getting my silver card. When I saw the Blood donor stamp on the envelope I thought it was my silver card arriving.
I'm gutted, genuinely gutted.
I'm going to appeal. They've probably never had anyone appeal before but I'm going to. They have to let me back. This isn't the end.
(I want that silver card).
