So Long Self - MercyMe

I like this song. Some of the lyrics are:

Believe it or not but life is not apparently
About me anyways
But I have met the One who really is worthy
So let me say

Chorus:
So long self
Well it's been fun, but I have found somebody else
So long self
There's just no room for two
So you are gonna have to move
So long self
Don't take this wrong but you are wrong for me farewell
Oh well, Goodbye, don't cry
So Long Self
