I really connect with this song, because I have been dignosed with manic depression, or bipolar disorder --- and lithium is a drug given to those who are bipolar. I hate the darkness and depression, but somehow I want to keep it inside me, because it tells me who I am. It's a part of who I am now, and it's the thing that has taught me the most about who I am, or who I want to be. At the same time, I wish it had never happened --- I wish that I'd enver have been diagnosed, or even had to be diagnosed. "Lithium, I want to stay in love with my sorrow... Oh, but God, I want to let it go."
