I am so sorry for what you are going through. I know how it feels like being in your shoe. But do not give up. I know of clinics that have no age restrictions. But it could have been better if you had frozen your eggs. That way you could be using them right now. However, do not give up. Keep on pursuing your dream. There are a lot of clinics out there that can manage solve your problem. Let the chromosomal defect not affect you. With technology this days nearly everything is possible. Do not look back. Focus on getting to your point of happiness. I was there once and I know what it feels like. You should not despair. Keep on searching. I know of a couple that had a child when the wife was 47 years old. So nothing is impossible. So whether you use donor eggs or not. Let the dream of becoming a parent never vanish. Right now you should focus more on having a family. You might be in love with your profession. But you should take a break and start a family.
