2001 Mazda MPV power issue.

I was replacing a cracked control arm and I forgot to turn my ignition off auxiliary. Of course, my battery died by the time I finished my little project. I attempted to jump the van, nothing. Went out and bought a new battery, only thing that works are the high/low beams. No window, no radio, no door chime, no interior or brake lights. Nothing. Turn the key to start it no sound.
