I've lived in a few places in CT. Currently in NW part of the state and seasonal depression is noticeable. When I lived near the water in Stamford, I did not have SAD. I lived in RI before that, did not have SAD.

I get through it by having lots of cups of hot broth, hot baths and making fires. This winter was mild so going out for hikes was helpful too. It is a huge challenge and my goal is to be a snow bird (go down south for 3 months) when my husband and I retire. That's nearly 2 decades away, so I'm in it for the long haul. If you can move, you should. It will be life altering.
