Are you prone to seasonal affective disorder? It's a known problem--seasonal depression. And, yes, vitamin D supplements can help.
The other treatment for seasonal affective disorder is sunlight. You can get a full-spectrum light box to sit next to; or you can spend a lot of time outdoors, or close to a window, or both. Most people feel some relief within a week of starting treatment with light therapy.
If those aren't enough, antidepressants or cognitive therapy can help; but if it's mild and not yet causing suicidal ideation or interfering with your ability to go about your daily life, it should be okay for you to treat it with sunshine. Light boxes can be had by prescription, by the way, and since they are such a safe treatment, most doctors won't mind prescribing one to somebody with the winter blues.
SAD? Maybe. I'm variously depressed enough all times of the year that I might not notice.
I showed up as mildly Vit D deficient on a routine lab test in the summer of 2011 and just ignored it; that was coming off a summer where I sometimes walked a mile to work and did a lot of social stuff, though usually in the evenings. My sun exposure during Fall 2011 to January 2013 was nearly 0. And, like I said, I don't drink milk. Could the problem have simply gotten worse?
All I can say is that I started feeling dramatically better after 3 weeks of taking Vitamin D supplements and getting additional sun exposure. If it's a coincidence, it could be bipolar disorder entering a manic phase. If not, I hope my symptoms continue to get better.
My parents claim I was nearly neurotypical in the summer of 2009 when I came back from nearly 6 months of military field training out in the sun -- and that I regressed after I spent the next two years in South Korea and Manchuria. Was it the field training itself, or something like Vitamin D that explains this?
