Tips on getting through a gloomy winter

Hi! I live on the east coast of the U.S. and lately, we've been getting a lot of snow. No, sorry, a ton of snow. Around this time of year, my depression gets way worse. It's gray, gloomy, and there's slush all over the place. I don't feel like going anywhere or spending time with friends. It's hard to spend time outside when everything is just so depressing. So...what helps when temperatures and spirits are low?

Here's a few helpful things I've tried:

- Growing some tiny plants! I buy those $2 grow kits from Target whenever I see them, and having something green in my room definitely helps a lot. Plants are great in general (even fake ones if the real ones are a little too much responsibility).

- Try a fun way to exercise indoors. I've been going indoor rock climbing lately, and it's a good distraction.

- Get outside, even if it's just for a few minutes. I try to force myself to take my dog for walks when I can, even if it's freezing. Fresh air is never a bad thing!

Does anyone have any other suggestions? I would try pretty much anything at this point. TIA :)
