CDG advice

In early May, I am traveling from Italy to the U.S.. I have a 2 hr 15 min layover in CDG. My flight from Italy to CDG is Air France, from CDG to the U.S. is with delta. I've read about how de gaulle is either an easy ride or your worst nightmare. Is that enough time? What should I expect? Will I need to re-check my luggage? I pray I am just overthinking things, but I at least want to be mentally and emotionally prepared in case shit hits the fan.
