99 expedition won't start

I have a 99 expedition. It ran perfectly fine
and one day I left the lights on and had to
jump it then when I was driving all of a
sudden it started stalling and when I parked
it, it wouldn't start back up at all. The battery
is completely fine it turns on no problem but
it doesn't even crank at all. The only thing I
get is a little clicking noise coming from the
fuse box under the dash. A while back I
noticed that the interior light switch would
only work sometimes and it would make a
repeated clicking noise when I would try to
turn them on then eventually stopped
working. I'm not sure if it could be a bad
ground or something like that
