Help me please

I'm hitting the bottom right now. I'm a new mom with a baby who I love more than life itself. I'm having terrible anxiety right now and I'm fearing something terrible happening to my baby or myself. I tend to feel the need to control situations so it's very hard for me to accept that I can't control whether my daughter or myself lives a long, healthy life. I just look at her and just love her so much it hurts. Please pray that I find peace.
