It's never going to happen for me

My husband and I have been trying for two years now. It's literally to the point where I get sad when I get my pre period cramps, ache, mood swings. We really want to be parents, but I feel like it's never going to happen. And I really just want to have my insides taken out, cause clearly I don't need them. I can't even walk into a store with out seeing a pregnant lady and it makes me jealous, so jealous and i just don't want to keep trying and failing anymore.. I want to give up, but the only way I would do that is of they just took it all out.
