1996 Plymouth Neon broken gas pedal switch?

I have a 96 plymouth neon and I took my neice and nephew to the movies last night and noticed it was overheating, so I turned the heater on. Temp went back down, a few mins past, driving at about 20 mph, I crossed the intersection and pressed on the gas to speed up. The gas pedal stayed on the floor, engine reving at high Rpms but no acceleration it just stayed at the same speed, immedaitly it jumped to high temp, (overheating), I freaked out and pressed the break, it took forever to slow the car, it slowed but not as usual. I used the E brake and put the car in Neuteral and guided the car to a parking lot. I turned the car off and left it there. The gas pedal is just laying there as if I broke it, no tension nothing.I'm to afraid to try and start. And its sunday so triple towing costs. I searched the internet and found nothing so far. If anyone could point me in the right direction that would be SO GREAT! The only thing I can think of is maybe the cable snapped? Maybe the pedal switch? But if it did wouldn't the Rpm drop instead of rise. THANK YOU SO MUCH TO ANYONE THAT CAN HELP!
