Overwhelmed

Hey ladies. We had our anatomy scan yesterday (21 weeks) and got some not so great news. We found out our little boy is missing a kidney, one of the two arteries in the umbilical cord is nonfunctional, the umbilical cord is at the edge of the placenta (and not giving him all of the nutrients he needs due to its location), and that he is now measuring almost 2 weeks behind after previously being a week ahead. Has anybody else gone through something similar? If so, how did it turn out?
