Miserable

So miserable. Cd 27 today and just got AF. Entering 8 months of ttc and I have hit the brink of having a mid life crisis. My husbands mom has breast cancer that has returned. So with the stress of that and baby making it is causing a lot of fights. He calls me selfish for wanting a baby and expects me to put my own priorities on hold. I am 34 and know that the longer I wait the harder it will be. I don't know what to do. I just wish I could live someone else's live. I have been trying to talk to my own higher power for guidance and am in so much fear that I will never be a mom.
