Weather, especially sunlight and temperature, or lack of it affects me significantly. My mood and energy seem to depend upon sunlight and temperature. If it is warm and sunny then I am in high spirits full of energy.
Does it affect you too to such extent?
Google it. There's lots of info on the web.
The weather has no affect on me unless the snow prevents me from going anywhere or it rains on my picnic.
Maybe it is something chemical. If you NEED sunlight, try a tanning bed.
Why do you think Seattle has the highest suicide rate? (Rain! Rain! Rain! That's why!)
