so stressed

So I just did my fourth round of clomid and I'm praying that I get pregnant. I had my daughter seven years ago but have had a horrible time getting pregnant again. I had a miscarriage a couple years ago and was diagnosed with pcos last year. And on top of being stressed and upset my best friend is now pregnant with twins and as happy as I am for it also kills me at the same time. I just want my daughter to have a sibling so bad and I just really want one more kid and it feels like it's not gonna happen for me. I feel like an asshole for feeling this way but I am just so damn sad and angry. 😭
