You battery is most definitely shot. Also, check your fuses and your alternator. Have you tried to jump start your car at all? You may want to do that. Make sure that once you jump your car, if it starts that is, to let it run for a while. Also, if jumping your car wont work, go buy a battery. If it turns out for some odd reason that it is not your battery, you can always bring it back. Hope that this helps.
