It sounds like you just have a dead battery.

Your problem may be that some circuit is still drawing power and draining your battery after the ignition is turned off. To check for that condition, you would have to disconnect a battery cable and wire an anmeter between the disconnected cable and the battery node to measure the current draw. Alternately, you can wire a test a light between the same points (light on means => current draw).

If you have a current draw with the ignition off, to find the circuit start pulling fuses till the current draw drops. Then it is a matter of investigating the components on that circuit and why is it drawing juice.
