Is this the end of the road?

I don't see how I am ever going to be able to achieve what my life has been about and the only thing that I've ever wanted out of life now, if a successful pregnancy is out of my reach then what is the point of living and striving for all the things that were only supposed to be there for when children finally arrived in my life, without children my life has no reason or meaning, there really is no point in going on, all the joy and meaning for me has now gone.
