don't know which genre of music you listen to, but after reading your post I recommend listening to "Let It Go" by Fischerspooner. It's the first thing that popped in my head as I was reading, and reminded me of the one I finally let go of. Definately takes courage to do so...but I found these lyrics motivating (maybe you will too). This song somehow put that silver lining around the cloud hovering over my head.
