As the title says. I tried in September and again in December to donate blood (it would have been my 16th blood donation) but my veins were just not cooperating and if the donor carer doesn't think they can get blood then they are no longer allowed to try.
It's upset me as I know only a small percent of those that can actually donate. Am I being completely unreasonable to not want to waste my time or should I try once more ?
