Legend of Zelda: Breath of the Wild has been helping with my winter cabin fever!
I live in Minnesota and we have gotten record-setting cold and snow over this last month. I've noticed myself getting depressed and angry about stuff much more than I do usually. Just by coincidence, I started playing Zelda more on my Switch. Somehow, making Link walk around in the nice forests and mountains has affected me outside of the game! I feel less pissed off! Give this technique a try if you're in the same boat I am this winter.
Also, I was about to sell this game because I hated it, now I'm loving it. No prior game has caused me to simultaneously love and hate a game. Weird.
Take your Switch outside, and run around Hebra for full immersion.
Being from Wisconsin... I can feel your pain. Video games do provide a welcome reprieve from being stuck in the house however.
If you haven't tried it, try supplementing your Vitamin D to get your blood levels to a normal range. Nearly everyone in the North has low levels of vitamin D and it causes Seasonal Affective Disorder.
My doctor recommended vitamin D, too! I'm not sure how much it helps cabin fever specifically, since I was already taking it, but my doctor agreed with you that everyone's vitamin D is low.
I got this feeling even more strongly from Far Cry 5. Which is strange because
A.) I hate the outdoors, and
B.) You run into gunfights every 20 yards in the game.
