Have 2013 chevy Cruze . Car overheated last night. Won’t start help please

What is your question?

Replaced thermostat a year ago, While driving last night car overheated. Turn off ac turned heater to high and drive protect mode came on. Had to drive short distance in this mode until could get to safe stop. Let car cool for couple hours, added engine coolant started car but forgot reshoot cap so coolant blew some coolant out but quickly shut car off, allowed to cool again and added more coolant, then car wouldn’t start, towed car home let sit overnight. had to add more coolant this morning as reservoir was low. Tried to start car- still won’t start, battery power saving mode on and now push start switch won’t turn off. Had to disconnect battery positive cable to turn all power off. Help please
