It matters how you think. Bipolar disorder and depression both affect the way that people think. In turn the way that people think affects the way they feel and the way they act. Cognitive behavioral therapy is a major tool in the treatment of mood disorders. In order to manage your disorder successfully it is essential to manage the way you think.
The Bible has words of wisdom on the subject: "... whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable.... think about such things" -Phillipians 4:8
