Love your quilts especially the second one, but as an Aussie it's lovely to see the one with Australian animals.
As for the weather getting you down, shut the blinds/curtains turn on all the lights. I know even here if we have a few days of rain or overcast weather I get a bit flat.
I don't mean to make light of your depression as I have suffered myself, but if it is just the weather try the lights thing. As my daughter use to tell me" fake it till you make it". All the best for 2013.
