EMARX - you're singing my song. Like Spidey, I'm also in the southern United States, so lack of sunshine and severe cold is not an issue. But, the funk hangs heavy upon me just the same. Everyone here has excellent suggestions, especially walking and crafting. The sadness hit me a couple of months ago - too much ISIS, in addition to the daily atrocities you heard about on the news (poor parenting, stupid people being violent, etc.). For two solid weeks I couldn't read, couldn't pray, didn't laugh, and considered getting on a pill (still actually kind of thinking about that). Two things saved me: 1) I started reading A Game of Thrones; 2) I started planning a trip. I don't know how your finances are, but this trip thing is what's really getting me excited. Find a place you want to go, it doesn't have to be far away, and research the hell out of it. Mine isn't far - just one state over, about a 3 hour drive. I travel a lot with my family, but this is MY trip - I'm going alone. And I'm going to pay for it myself by selling crap on eBay and scrimping and saving until I can pay for it. It's only going to be for a couple of nights, but wow - three days of being on my own schedule, cooking what I want to eat, staying up until 2:00 a.m. and watching stars in silence - bliss. (My family doesn't know about it yet, and that's part of the fun.)
I hope you can find something to get you excited, EMARX.
