Had to answer this one.
I'd have to say "Goodbye to You" by Michelle Branch. I don't really know if in a good way or a bad way. I guess both. Bad, because it reminds me of Sean and what he did to me. Good, because it is the song that gave me strength when I decided to cut him out of my life. So while it is terrible to think about the abuse, it's also good to reflect on the power I gained over the situation and how I have overcome a terrible situation. I am a survivor. And that song speaks to me as a survivor.
