You do NOT sound like a horrible person! What you are feeling is totally normal and healthy and just goes along with the unfairness of infertility. My sister (who is a wonderful Mom in a wonderful marriage) announced 2 pregnancies while we were TTC. I bawled for days each time, not because I wasn't happy for her, but because it was so hard to watch them fill their house with children while we sat here in our silent, lonely house waiting for a BFP. I'm so sorry that you are having to deal with this on top of everything else...it stinks and it is completely not fair.
