Sunlight and what I call 'high visibility conditions'

makes me feel worse, but as the day grows older, and things get dark, I do feel better. I'm a night person, mostly because I can hide better at night, and it seems like the skies outside reflect how I feel, and I like that better than when it's sunny outside.
I do hate waking up and getting out of bed, but keeping busy somehow will help, I also have this 'lingering sadness' it seems it will never go away.
