Not just you. After about 2 years of unsuccessful IF treatments, any pregnancy announcement brought me to tears. My DH didn't quite understand, so I had to spell out that while I was happy for my friend I was 10 times that sad for our shitty luck. By year 3 when I was coping better, I'd tell him and he'd say, "Oh f*ck them!" LOL He finally didn't think I was horrible and unreasonable anymore.
I wouldn't wish infertility on my worst enemy and I hope everyone finds the families they were meant to have...however that looks. Chin up, OP.
