To love the thought of longer days coming? It's actually the only way I can get over Xmas.
I've always suffered from SAD, and the past few years from year-round depression, mostly well managed via medication. But I had a fairly miserable childhood and Xmas was the worst time in my house for rows and violence. Somehow the way I felt (as a child) every December feels like it's baked into me! I anticipate a miserable time, even though logically I know my lovely DH and adult DC will make it a perfectly nice time.
But this year I've focused on the thought of having a tiny bit more light each evening. By New Year's day we'll have 10 more minutes of light. By end of January it'll be approx an hour of extra daylight. Bring it on!
