When you're looking for some comfort, here are some of the things that work for me:
Bob Marley - For some reason these easy going tunes are very soothing to me. I take to heart the lyrics "Every little thing's going to be alright" in Three Little Birds. In the end, everything will be alright.
Popcorn and Tea - This is a nice snack to have in the middle of the afternoon when you're feeling dreary.
Watching an old TV show - My shows of choice are Sex and the City and Downton Abbey. I find that familiar shows where you know what's happening make me feel better. You can simply space out and forget about what troubling you for awhile.
I wrote about comfort food here. Things like grilled cheese sandwiches and ham dinner.
And I'd be remiss without mentioning some comforting bible verses that always help me.
