Do any of you get very very depressed?

Ttc for so long is taken it’s toll on me. Every person I see with a bfp makes everything worse. To top it off. My ex husband is having a baby with his new wife (we have two kids together as well) and here I am struggling for a year now with pcos and long ass cycles. Sometimes I just wanna curl up and not exist anymore. In no way am I suicidal but I just don’t wanna be alive sometimes. My husband doesn’t understand what I’m going through. He thinks everything will just magically work out in the end but I’m also not getting any younger. Ugh!!!! Everything hurts so bad when all I see is bfn after bfn! Anyone else? Do you have any advice?
