TTC struggles

How do people cope when they see others getting what they want?

My husband and I have been trying for a few years now. We have been to doctors, they don’t see any problems apart from the PCOS.

I have now have beautiful three nieces and a nephew, and I love them so very much and love my sisters, but I envy them so much!!

Does anyone have any coping mechanisms to help?!?! I just wanna cry!
