well that is life, some will HAVE children and some would NOT have. It is unfortunate but thats life. Some will die as a result of cancer, others peacefully while other from a heart attack. Whatever your lot is in life, accept it in good stride and be happy. Life does not start and end with children. If you desire children so much try adoption, IVF and the likes. Afterall some people had children and didn't want them and abandoned them and are living their lives fine. This is not to discourage anyone but if you are infertile then that is it. Keep trying and go for testing but if you're sitting there waiting and youre infertile then you are on your own
