Trying to be positive

Does anyone else get mad when you see other people get pregnant? I mean the ones that have been trying for years and stuff I don’t but if your 16 and pregnant I get pissed! I mean your still a child your self! Husband and I have being trying for 2 years, had a miscarriage November last year so here we are again! Trying to get pregnant and taking negative test and not ovulating get tiring really quick! Sorry for the rant but I had to spill lol ( I try really hard to be happy for everyone)
