What happens to me every winter as I deal with S.A.D. Seasonal Affective Disorder. It causes depression from the cold and not having any sunlight. Can you buy yourself a sun lamp? That may help a lot. My depression is not as bad in the spring and summer months compared to fall and winter. I hope this helps a little bit.

Have you heard of Kratom? It helps me.

Might be worth a try

I feel the same, Have you tried light therapy?
