I used to live in Seattle and felt like how you're describing constantly! My decision to go to school in California was actually very influenced by the weather :P
I don't know but personally, I talk with "normal" persons with no anxiety, and when they drive with cloudy weather, they feel "asleep", or less vigilant. With anxiety, I think we misread this signs and It activate anxiety and panic.
RIGHT!? Why does it get worse? ESPICIALLY while driving?
Well i have depersonliazation which doesn't help anything.. and I'm completely terrified to leave my house.. I'm agoraphobic.. I'm working on it though, do you have any advice you could give me?
Don't feel alone abt 2 years ago I was the same way id say 2012. When it would rain or be cloudy I would be so depressed and just blah and it isn't a good feeling. Have you always been this way? I'm happy I'm at the point again that I can except the rain and ugly days some time it's fun maybe turn on the fire place or heater and get some nice warm hot tea or hot chocolate and watch a nice movie. Godless pray you start feeling better
