I have given blood before, it's not that bad and if you want to you can have a local aneasthetic on your arm before the needle goes in. So if you dont look then you probably wont even know it's there. It take about ten minutes from start to finish yet it could save anothers life in a split second.
I cant give blood at the moment and feel guilty especially when all the leaflets and letters come through - i have asked to be taken off the mailing register but apparently they only stop post for 6 months then it starts again. I am ARnegative so i know they need it but they cant have it but that makes me sad
but if you even think there might be a chance you can stand it please try and give blood - if you get on the bed and really cant do it then just say so - chances are you will go through with it anyway and it is a great feeling to think you could save a life x
good luck
