This is about depression bringing you down all the time, sometimes for no reason, while someone or some people try to tell you it's easy to be happy because they don't understand how depression works. In the second verse, there is a reference to my favorite band. There is a song called "For A Pessimist I'm Pretty Optimistic" by Paramore. (The title is never said anywhere in the song). I reversed the title and made it them opposite and it's the second line of the second verse. I am sometimes an optimistic but only for other people's lives. Second verse also features the "F word".
