From my studies I have come to believe that where what we call "faith" is in the brain is very close to where disorders of the mental state are too... meaning that nearly everyone I talk in depth with who has a mental unwellness also has an issue believing even what they used to believe about God and love and faith and all that.

I like the phrase don't doubt in the dark what you knew to be true in the light. Making important decisions once you have mental issues is not the thing to be doing especially regarding your faith (or changing your faith.) That may be your disorder causing it and not what "YOU" really believe.

I believe that just like any purely (if there is such a thing) physical illness, emotional instabilities can cause changes in the body and mind (or soul). While the causes can be different (say, allergies versus irrational thinking) the results are similar: the body suffers.

Ok got to run...will check back later
