Feeling lousy and incompetent at 31+ weeks with pre-eclampsia & GD

Hello! I’m at 31+ weeks with pre-eclampsia and gestational diabetes. Although I don’t exercise, I’ve been trying very hard to watch diet and keeping blood sugar in good check, but the conditions doesn’t improve. My baby is most probably due by C-sect anytime now should the doc deems fit and will require NICU (private rates). I worry for baby’s health and the hefty costs to be incurred from NICU. I have very supportive and encouraging husband and family. But I cannot help feeling lousy and incompetent and seems like nothing is within my control. I stopped talking to baby for a while because I’ll cry when I do so. Even now as I’m typing this I’m tearing and I’ve been having sleepless nights. What can I do to change my mindset and be positive and not transfer my fears to baby? What more can I do to ease my body conditions and to reduce financial burden? Thank you everyone, I really really need help. Thank you.
