I was under the impression that people who got depressed around Christmas did so because it brought up memories of Christmases past, be they happy or sad memories.
Christmas is fun! Giving presents is fun! So is receiving them!
Seriously, if you're not big on Christmas, just treat it like any other time of year. Just be happy it's not Easter. Now THERE'S a depressing holiday...
