Hi Zee... yes, winter is a tough one. Fortunately, compared to Scotland, London can still feel reasonably mild in October and sometimes November. The autumn colours soften the start of what could easily become potential misery.
Come December, decorating the flat with Christmas tree and lights with loadsa candles, maintains cosiness. Without doubt, Jan and Feb are the worst months, but try to spoil myself with decent food and heat. I also make sure there is warm clothing for outdoors.
Unlike Pip, I love a good downpour; it has pleasant memories of my hometown, Glasgow. Now, there’s a place to make you depressed in winter!
Zaf's idea of a light clock sounds good. Last winter, getting out of bed at first light, and taking in as much natural daylight as possible, did make a difference. My flat is top floor and very bright. Ridiculous gas prices make it expensive to heat. But, I prefer to spend a little more and have everywhere comfortable and warm.
I normally stay outdoors every day, at least 2-3 hrs with the dog. Unless I'm particularly paranoid and agoraphobic. That usually comes with depression, so my MH throughout winter, can easily spiral out of control.
This year I might try Vit D supplements, as Zaf suggests. I think the glare of a light box would irritate me… Do you know anyone who might have one you can try?
Let us know if you get one… Do you know the cost?
