I tend to only get SAD when I'm at school. When I'm working, I'm around people and I'm doing the things that I love. Being around said people get me out of it usually. When I'm at home or living on my own, I tend to be more depressed. That being said, I still think it's a mind thing. I was on the B12 and Vitamin D pills, I got tired of drinking a whole glass of orange juice all the time, so I stopped. It didn't really make me feel any different. My doctor told me to start taking them, so I did.

I love winter. Absolutely adore it. Also with my commute (All 6 hours of it, plus a walk), I find I'm getting out/walking a lot more. I also try to keep my phone in my pocket rather than in my hands more often. It tends to help. It has been cloudy lately, but my depression doesn't depend on weather. It depends on my hormone fluctuations and what happens in my day.

What I suggest is that you find something that you love and stick with it. Winter can be a downer for people if you let it. Just living in general can be a bloody downer if you let it. Find ways to make it good for yourself. That's how I combat depression lately and it seems to work for me.
