Mental break down

I really feel like I’m on the verge of a mental break down. So many of my friends are pregnant and I am so unbelievably happy for them. I’m just struggling bc they weren’t even trying. My husband and I have been trying for 6 months. With 1 chemical pregnancy. Which that tore me down for a little while. Nothing like getting your hopes up for it not to work out. I’m on the verge of having a mental breakdown. Every time I see someone post about their pregnancy I literally start bawling. How do you cope with this?
