Depressing 😔😔😪

My husband and I have been trying to conceive our first baby for going on 8 months and we have had 0 luck. Then his cousin who is married and has a kid starts telling family she wants another baby n walla! Within 3 weeks she's pregnant. I don't want to be mad at her but she is always trying to talk about it and whatnot asking why we haven't had a baby yet then she just rubs it in my face that she's pregnant. I just want to cry when people ask why I'm not pregnant yet... Idk why we are definitely trying! Some say quit trying n it'll happen but all of you on glow know how hard that is when you want it so badly to be a mother... I'm happy for her but feel jealous that she got pregnant so quickly when we've been trying for so long n had no luck 💔😟😢😡😒😵😵
