Anything?

Hello everyone. I am brand new to the forum, hope everyone is well. I have recently purchased a 12 plate Nissan micra 5dr. The car when purchased had two damaged passenger side doors. It arrived dead but with some jump leads it was up and running. Today I removed the back door and replaced it with a new one. There were only two wires inside to connect, the speakers and central locking. I haven't done anything else to the car. Now the issue, I was putting the door panel back on and for some reason the headlights came on with the light switch turned to off. The headlights stayed on until the battery died. I tried jump starting the car with leads but nothing. Completey dead. No light no nothing. This is as far as I've gotten with it as it got dark and I was in my driveway. I would love some advice on this issue. Could it be a fuse or has the battery fried? Or have I done something wrong with the rear door? Any advice will be much appreciated. Thanks everyone
