I had absolutely no power and I couldn't even jump

No Power? Do you mean that the engine would not crank when you turned the key? Did you have dash lights? Dome lights? If you had some kind of lighting, you had electrical power. and if that is so then it sounds like your transmission range selector switch may be faulty or needs adjustment. Or VERY POSSIBLY, you might not have put it ALL the way in Park when you turned the car off the last time. If you try it now does it start? If not try putting it into park a little harder. Does that work? If not put in Neutral and try it. If that works the Gear selector switch Is bad or in need of adjustment.
