It is not easy to overcome, especially since it seems irrational.

I think that the situation is different where you have to be the sole caregiver versus when others are around. In the former, people seem to rise to the occasion and take care of the situation, while in the latter our emotional responses and fears are more likely to kick in.

I have never liked to give blood, but force myself to do so. I have passed out before because of it, but now I find that if I have an ice pack on the back of my neck to start with, then it is much better. But the best way is to think of other things. So if I can have a conversation with someone else while giving blood, it is an amazing difference.
