I have a question. I've been in Seattle 4 years now. I can take the cloudiness. I can take the rain. I welcome it.
What I can't take is the summer sun. The unrelenting, clear, cloudless days. I find no joy or comfort in them at all.
Is it possible to have reverse SAD? My son and I both seem to have this problem. I truly don't even want to leave the house when it is a bright day. This was never a problem when I lived on the east coast, where I really think the light was a bit dimmer than it is out here, but maybe that's just the comparison between the usual greyness and the summer.
Do other Seattlites have a problem w/the sun?
I haven't heard of a 'reverse SAD' as a recognized clinical condition, but what may be the case is that you, like most longtime residents of Seattle, have simply acclimated to what is the norm here, and so sunshine then becomes abnormal and therefore less-friendly.
As for myself, I also tend to be happiest on the grayer overcast days mainly because of the cooler temperatures. I tend to sweat when it gets even mildly hot and am made terribly uncomfortable by what most Texans would likely consider an 'average' day.
These are just guesses on my part, and if these conditions are negatively affecting the quality of life for you and your son you may wish to consider getting help. This might be a good place to start:
