My personal experience with milder form of depression, is that you can significantly help yourself by stop taking your thoughts that seriously. Everything you think about yourself and the world is just thoughts. So it helps if you go meta - i.e start thinking about what you are thinking. In the article, one man had constant voice in his head ordering him to do stuff. If one is able to look at it from another angle, and to instead of trying to do stuff the voice tells, for example start marveling at human intelligence that is able to think in sound! Not just sound, we can think in all the ways we experience the world. Through abstract thought, sounds, visually, through movement ... Help yourself, go meta :)
