Did I break a head gasket?

What is your question?

My vehicle is a 2002 Hyundai Elantra, On the way home last night it made a loud pop on the highway and white smoke was coming out. Before I pulled over my dash showed the battery warning light and then all the electronics (Radio, headlights, etc.) and power steering went out. When I finally did pull over to check the engine it looked like coolant had leaked out all over the place. The smoke smelled kind of sweet? I'm not sure if this is a blown head gasket or maybe just the car's age?

What makes this problem better or worse?

Haven't turned it on since yesterday (4/22/19)

How long has your 2002 Hyundai Elantra had this problem?

Only just now
