Away from baby

Tomorrow is my first day away from my 8 month old son. His bio dad is taking him for 2 nights (court orders) and I'm freaking out. I don't trust him at all and he hasnt seen my son since be was 2 months old because he raped me and multiple underage girls. I havent gone to the cops because i simply dont know how to.

I'm so scared because ive never been away from my baby and hes never taken care of anyone before. I literally feel sick just packing the diaper bag. I dont know what to do
