Update on my winter-sadness

At fall's end, I checked out a DVD about seasonal affective disorder.   I watched it and decided that I do not have SAD, but rather what I call winter-sadness.  The cause of this sadness, is the lack of color--the grays, whites, blacks of winter.  My mood lifts when the sun shines, no matter what the temperature.  If it is snowing/blizzard and I am stuck in the house, I feel hemmed in.  Since I am not bothered too much by winter-sadness this year and I am not as preoccupied with myself, I am noticing it more in my work colleagues and the phone customers.  The sadness might take the form of a work colleague not wanting to be at work, or quickness to feel a hurt.  Perhaps this winter I will reach out since I am not so focused on self.
