I can relate to you on some level. As a teenager, I was a panthiest; now I'm a christian. The passion and desperation of both of the religions I have followed have been felt by both very intense manias and sometimes very intense despair. The intensity and increase of my bipolar symptoms have pulled me from the shadows of doubt and into the lightness of reality. My beliefs are the way and no one can compromise them when I am either in the depths of a mood or especially when crawling through psychosis. I have known far too many conspiracy theories when psychotic. Sometimes I have even know my deity on an unreasonably personal level and other times I believe I have solved all the world's problems.

I don't have many answers to your question, however. Medication, which I know you strongly oppose for yourself, has sometimes pulled me from this. Mostly though, it is just letting it run it's course. This for me can admittedly take months and months at a time. For me, bouncing my thoughts and beliefs off of someone else while I am still lucid can help stop the succession of madness.
