Feeling fragile, probably bc I am 😳

I have been ttc since April of 2016. My best friend started in January of 2017. We talked about everything regarding our ttc journeys. Today she tells me she took a test this morning and got her BFP. I am so happy for her, and so sad for myself. I could tell she was afraid to tell me but we told each other that we are in this together. I worry that stress is what is keeping me from conceiving. My job and current custody battle with my stepsons mother has me at a legit breaking point. I started clomid this cycle. We BD every other day....when is my turn? When will I be a mother? Ughhhh why why why???
