you have to stop thinking of it as "yours" because the only thing that is yours is the egg. It isn't a person inside you, it isn't even a person yet. If you where donating a kidney would you still consider it yours even if it is another body working fine?
might stop thinking of yourself and more of the people you love. How much joy this would bring them. I could get over myself for that. I also think it is a beautiful and selfless gift.
