I have heat intolerance and have never liked the sun and heat.

I love cold rainy days. A/C is always on full blast. I love clouds and overcast times, even thunderstorms (minus the lightning if I'm outside).

Sun and light are not mood boosters for me.

I don't consider sunny weather to be "good" weather. It's the worst kind of weather. Rain is good weather.

Maybe it's something like what MOCS suggested... or maybe it's something like me.
