big decisions help please?

I'm moving 25 miles away from current home to be closer to my job and to live with my bf...only my 9 yr old doesn't want to change schools and his visitation with his dad is horrible..cps is investigating his dad and his gf and her kids bully my son horribly.

His visitation is whats causing problems...I have to live my life around his schedule as it changes week to week and I never know in advance when he's going to see his dad or what time or anything. It could be wed and thurs or fri and sat or wed and sun or a few hours here or there...some overnights... I'm getting a petition to modify the visitation..but what do I do in the meantime? I am literally sick over this... my son is going to need trauma counseling as a result of what is going on I just need some advice...I cant afford a lawyer.
