Pregnant after loss and terrified

I am 4w 5 days after a missed miscarriage in March. I was 18w along but baby had stopped growing at 14 weeks. I am so scared and it just doesn't even feel real to me at times. I feel so disconnected and I can't even acknowledge I am pregnant-I try to just push it out of my mine because I am so afraid to become attached and go through my heart break all over again. We were not really trying for another pregnancy so soon and this is just a shock to my emotions that maybe I am not ready to handle. Any other momma's feeling this do you cope?
