Could the pain and sui feelings be coming from the breakdown of a fantasy and emergence of what you know is the truth? If people here are echoing things you already know inside, and don't want to accept, then that would feel undermining even though from what I've read, everyone here is pulling for you.

Here are the things worth cheering about:

Putting the well being of a child above all else. (BIG congrats on that.)
Being honest about your situation. (That takes GUTS.)
Being open to feedback from your professional support as well as here on PC.
Asking for what you need.

Lean on that and ignore the despairing side of you that says it's all pointless if you don't have a baby right now. You have a lot going for you. Including a ton of support right here on PC.
