help

my baby is two days old and was born at 37 weeks due to being induced for high blood pressure and bad headaches. my baby got choked on my boob and turned blue and stopped breathing and we had to go to the hospital but i'm traumatized. she’s okay now but i can’t stop thinking about something like this happening again. i can’t keep my eyes off of her. i’m terrified to even go to sleep. has this happened to anyone??? any ideas on how to calm myself down??
