Miles on amg

Hi would like to ask for help

I had recently snapped my belt while driving and my car was still running and had to make it home I was like 5 mins away the temperature on the car reached 120 and I was 2 mins away before reaching my house and as soon as I did I shut it off there was a coolant leak right where the drain hole is and then the boiling sound from the water being hot and that was all the issues i saw and was wondering if this could have damaged the head gasket or any others parts of the engine
I know I can start the car with out a belt but em to scared and em waiting on a new tension pulley wit the idler pulley as well
