No longer TTC, feeling like I'm mourning

So I had a miscarriage a few months ago which may be adding to my distress. My husband and I were beginning ro try for baby#2 but we just had some bad marital problems and I've decided I don't want to TTC anymore.

I know it's the right thing to do, but I feel like I'm mourning that baby along with my miscarriage baby. That baby would have been born in December, but with this one we were hoping for a may-september birth.

It's just sad when I had been so excited to be pregnant again and expand our family.

Anyone else experience feelings like this before?
