Losing hope

Does anyone else ever feel like giving up? It's been 11 months of trying  we got pregnant in August and lost it in October. 
My husband isn't an emotional person and doesn't seem to feel any of the stress and heartbreak I feel. I feel completely alone in this. He doesn't want to know when I'm ovulating because he feels pressure but then there are times I can not get him to have sex at all when we need to. 
I'm also a labor and delivery nurse and everyday I just see what I don't have and the bad outcomes just remind me how you can lose your baby suddenly at anytime. 
Each month that I get my period breaks my heart all over again. I'll be 30 next year and I know all the risks that increase as you get older. I just don't know if I can do it anymore. I know a year is nothing compared to what some of you have delt with and I don't know how you do it.
