I read Olivia Lopez's blog Lust for Life a while back and she wrote a post about listening to sad music to just wallow and I honestly thought I was the only one.
Most of these Fill the Silence playlists have sad songs. I get into my sad song spiral when I start listening to Daughter and then Bright Eyes. When Adrian comes home and Bright Eyes is playing, he'll see me sitting in the dark, maybe crying, or just listening.
It's these quiet, reflective moments (that you might think are strange) when I come out feeling refreshed and re-energised (sometimes).
