Only just found this post. I think it's amazing that people are signing up or considering signing up for this. Caroline, I think you did the right thing signing up now, it's great motivation to loose the weight, plus, like you said it's not instant, so you will easily do it.
My brother got Luekaemia when he was 5 and needed a bone marrow transplant. Luckily we didn't have to wait for a donor because I was a match. It was quite unusual because he is actually my half brother, but someone was shining down on us. I was 12 at the time, and I happily did it. Since then though I have had a huge phobia of giving blood or anything like that. If I need a blood test I literally pass out for 10 mins. It's not the needles that bother me, its the actual taking of something that is in my body. I'm sure a therapist would have a field day with that one!!!
I can't give blood, and I defo couldn't donate bone marrow again. It just won't happen.
I think everyone that does go on the donor list is amazing, so hat's off to you guys.
I have a donor card, so when I'm dead they can take absolutley everything I got. lol!
Oh, and my brother recovered after 4 years and he is now 21 and unbelievably annoying!!
