There is a line in "Clean", the last song on "1989" – 'When I was drowning, that's when I could finally breathe.' It talks about the loss of a relationship, but it could be about addiction, depression or the loss of someone. There's this quote in [the book] The Fault In Our Stars, 'Pain demands to be felt.' No matter how many times society tells you to put on a smiling face, pain is going to be felt one way or another, today or a year from now. I've seen people go through incredible difficulties and the ones who faced pain head-on made it out quicker than the ones who pretended they were OK.
