Guilty disappointment

I know this probably comes up a lot and can be a sensitive topic, but I am struggling with severe gender disappointment. My husband and I have always pictured life with baby girls. We had a name, and kept calling baby by it. We even had false hope by an incorrect Sneakpeek which said it was a girl. But we received our NIPT and the result stated its a boy. We are heartbroken and I feel like I'm mourning my baby and don't feel a connection to this pregnancy.

I get so jealous with seeing posts of women finding out their having girls, even when they're facing their own disappointment from wanting boys.

I've been crying for 2 days and feel numb and am worried I won't be able to bond with baby. I have tried therapy in the past, I am on medication for anxiety/depression. I just kind of feel lost right now. This is our first baby so I'm scared.
