How do i cope with my high risk pregnancy.?

I'm in my 29 week of pregnancy with my second child. I have had excessive amniotic fluid for the last 4 to 6,weeks. We found out yesterday that our baby has a bowel obstruction and that there is a possibility that I will be going into preterm labor or he may have to be taken early. I am having a hard time coping and don't think I have the strength to cope with seeing my baby go through surgery and in the nicu. Has anyone out there had a baby with birth defects? I feel so alone. How do I cope and stay healthy for my baby and 3 year old?
