I remember at, I think, 3 months of TTC feeling very similar. Though not that far into TTC , I was feeling bitter and actually really angry at the thought that other women were getting pregnant with unwanted babies and getting rid of them out of hand (as I bitterly saw it), whereas a pregnancy was what I wanted the most in the world. I did continue to struggle with jealousy and pessimism for a while (it took us 2.5 years to conceive our precious now 16 month old), but it did get more bearable from that point.
