Jealousy

How many of you experienced a roller coaster of emotions within seconds? I am now 7 weeks post missed miscarriage (Baby stopped heart beat/growing at 7 weeks)and a close friend at work posted that his wife is expecting their first child. She is due the same month I was supposed to be due 😭😭😭. I went from “wow, congrats that’s awesome” to angry, to sad, to depressed, to withdrawn, to wanting to know why them and why us? I am genuinely happy for them but also still incredible jealous. Does anyone know when this will end? Or does it? Does it ever get easier?? There are days I feel normal and then something small sends me back down the rabbit hole. I don’t want to become a bitter person but I just want my baby back.
