Antifreeze leaking

Suddenly after washing car went to vacuum and saw lime green fluid draining from front of car. The overflow has orange though. The only leak I could see with brief look was right before the overflow. Can't tell exactly where from under car because fell on ground in two spots, but I have a skid plate so it was coming off that so couldn't see exactly where from car itself. Car doesn't register hot. Past two weeks gas has been going super fast though and some white smoke from tailpipe. Also two weeks ago car would shut off upon slow down or stop. It stopped after two days though. Doesn't seem to have as much power behind it when driving. Like cuts out almost. Sometimes it does smell hot and codes read it's burning too rich. Also when starting car it begins with super high and rough and loud idle. You have to push gas few times to get the rev down.I'm single mom recently and this is literally the only thing my kids and I have so i'm panicking and stuck.
