As a religious individual (not only Christian), you're often expected to control your desires, pain, anxiety, suicidal or homicidal thoughts, emotions and other possible symptoms of mental disorders (the mind in general) with your faith. Some even believe that not doing so is a sign of weakness. In such case, what do we do when our minds (brains) are broken or defective? You'd need medications to control random emotions and over all psychotic behavior.
One thing that's come to my mind again and again is trying to be a good Christian while mentally ill. It's difficult when the demons in your head are constantly trying to poison or simply kill you from within (http://project05952381.blogspot.com/2009/01/so-alone-in-my-journey.html).
