Like you, Bre, dismal winter days can suck all the life from me. Living in Florida, we are fortunate not to have much weather like that in the winter months — in fact, our days are typically sunny, even when cold. But, I grew up on the coast of Virginia where winter was gray and brown. I don’t miss that.
It’s hard to shake winter blues, especially when there are underlying reasons for your sadness. Your poem perfectly describes those feelings. Surround yourself with as much color and light as you can and write, then write some more. I hope your mood improves soon.
