Grieving my pregnancy loss from PPROM

I am really struggling 4 days postpartum. My daughter was born more earlier than I expected due to PPROM. She is doing remarkably well considering. I just worry of the shoe that may drop. I cry, I get pissed, I cry some more. I am sad that I didn't complete my 40 week pregnancy journey. I feel robbed of what time I would have with her inside me. I feel robbed of the maternity photos I was in the process of setting up, the baby showers with my big bump and ppl guessing my roundness of the baby bump, buying more maternity clothes. The greatest pain I have is watching other new moms take their baby gone and I had to go home empty handed. It just isn't fair!
