I think this song is about Mika's relationship with his parents. I'm not quite sure what he means by looking for joy in the "back of the bar," but I think it's about his parents not understanding him. (Mika has dealt with this topic before. Consider "Stuck in the Middle") "Dr. John" is a psychiatrist that his parents are talking to to understand what they did wrong with him. I think when he is talking directly with Dr. John, he's meeting with him himself.
