...cold weather make you feel melancholy or as if something is missing?

It's winter outside. Had the doors and windows open for a while to air out the place but when it started getting cool, there was a strong urge to run and close up everything real quick and maybe even hide under my blankie. As I was closing up, I wondered what I was protecting against. It wasn't just the cold. If I had a fireplace, I'd light a great big fire in it. Even so, there's still something missing and I can't put my finger on it. I'm getting flashed of my childhood of when my mother would close everything up but whatever is missing now, wasn't missing then. ... As I look at that scene from my childhood, there was a light then that isn't here now... even if I turn all the lights on. I don't know, but the tears have started and I can't figure that out, either.
