Tigerlilly,
There are lots of resources on the research thread in the stickies above about the bipolar spectrum. I've read most of them. There is no place that suggests that a belief in a Higher Power indicates one has bipolar condition.
Now, if one believed they *were* the Higher Power itself, well, that *could* be a manifestation of the grandiosity often seen in the manic stage of bipolar I disorder.
Please take a few minutes and read about the spectrum in teh research sticky above. I particularly like the
Bipolar II, Mood Swings without Mania; Brain Tours; Stress and Depression; Hormones and Mood; and more... one and teh NY Times one.
Hope to see you around more.
Shalom!
