I've been fighting back by going outside as soon as the last kid is on the bus, camera in hand, dog underfoot, catching sun everywhere I can. There's still lots of lovely leaf colors if you look low and close, and sparkles everywhere.
Today I brought some leaves inside and played in front of the window for a while, catching them up close in the light. I've probably taken a thousand pictures this week, but it's cheap entertainment. I keep thinking I'd like to paint some abstracts like these bradford pear leaves, if I were a painter. They are amazing, and they fascinate me with their blotches of colors and white veins.
When the sun is dipping behind the trees, I make sure I notice, and if there are some pretty clouds, I run out and snap a few shots of the sunset too. There may not be much daylight to work with, but I'm paying attention, using all that's available, sunup to sundown. I'll get through, I always do. I'll sit under my full spectrum reading lamp and eat my vitamin D and try to exercise and bake and make soup and meditate and not go crazy while the days get shorter and colder, until we start the climb back to warmer, longer days. And I've got all this sunshine saved on my hard drive to look at any time I want, and some pressed leaves to look at and remember.
