You'll get through it, be strong for him even if you feel like you have been kicked so hard it has winded you. You're going through a trauma and the human body is very resilient. You will cope will little sleep, however I got a little something to help from the Dr to put me out, it's was only for the worst bit so don't feel bad if you need some of the hard stuff. Failing that a large glass of wine helps wonders too :-)
You'll come through this as I think I will to, I survived the trauma bit now I�ll get through the recovery bit and so will you and your husband.
