Ttc- feeling like its a waste of time:-(

Nicole
So husband and I have been having unprotected sex now for almost a year. Before that we tried for 8 months and decided to hold off till we were married. 
I feel like such a failure now, nothing is happening and it just feels like it never will. I feel like a childless, aimless old woman. I've spent years trying to make my life better from a crappy white trash family and it seems like by doing that I've left TTC too late. I don't believe in God or Jesus or praying so literally have no hope or avenue for this horrible feeling of inadequacy. 
I'm taking a career break soon as there has been a lot of other things going on and I feel like I need a break. What do you guys do when you feel like giving up?
