I’m not sure where to turn??

I’m 4 months pp with my 2nd baby. I’ve definitely felt like my anxiety has tripled since she was born. I’m by myself most of the time due to my hubby’s work schedule. He has to sleep all day to work 15 hours over night 4 days a week, sometimes more. I live over 500 miles away from family, and have no nearby friends. I’m going CRAZY. Especially lately my baby girl won’t let me set her down, for two seconds, even sleeping. I can’t eat, change clothes, brush my hair, even pee without her screaming her head off. I start to cry and shake and turn into a full out rage, and I even smack myself in the head sometimes. Because so badly I want to call out for help but there’s no one there. I’m scared to talk to anyone honestly because I fear dhs being called to my home. What on earth am I supposed to do? I know I can’t be the only one. I need help. Please.
