Glad everyone is fine. To add to the rest of the advice is to check the lug nuts/bolts after getting the car back from the mechanics. A lot of time they will forget to torque them down. I always redo mine when I bring the car back from the shop with a torque wrench. Sometimes shops wont tighten them enough, and sometime they will over tighten them! Could be a honest mistake, but its not them that will suffer when the wheels fall off.
Back in the days, my dad got his brakes done at a well known shop in Montreal. He drove to toronto the same day and upon reaching, he told me he kept hearing a weird sound. I check the wheels and I was literally able to spin the lug nuts with my fingers. Scary!
