geekylotus, I'm studying to get my degree in psychology and doing meditation research right now (trying to incorporate buddhist psychological principles into Western Psychology), so may have some insight into your question/problem. i think your aversion to religion is actually a quite healthy development -- it seems to me that religious zeal and delusional/irrational thoughts can be the cause and the result of the innacurate thought processes we associate with manic or depressive states, and so you are right to associate religions and religiosity with the sort of thinking you and all of us are trying to get away from. fortunately for you, and for all of us, buddhism is not a religion in this sense. in buddhism, there is no God, no irrational faith, and the focus is really on having an accurate, non-deluded view of the world as it is. in fact, the buddha encourages people to doubt his teachings, to "go see for themselves," to not just take it as some sort of faith based delusion we should follow by some moral imperative designed by some god we've never heard of. we all have delusions of some sort, self-serving biases, overblown perceptions of bad events, persecutorial or egocentric fantasies -- everyone has these things, bipolar disorder is just one set of fantasies going to an extreme in both directions. what the buddha tried to do is to devise a proper way of viewing the world which would help us to sidestep completely all the pain and suffering caused by these delusions. so, i think you are on the right track in doubting religion, but also on the right track in checking out buddhism (which i've always thought of as more of a philosophy than a relgion; even many buddhist monks have said or told me personally that buddhism is not a religion). i have met many people who have said that buddhism has helped them to understand and work through their problems with bipolar, and I think that initial inkling you had towards Buddhism is a shimmer of you're understanding of why.
ay, i don't mean to sound like a religious zealot of any sort, i would never even call myself a buddhist even though i've studied it quite deeply: i've just seen how many times it works for people in conditions like yours and mine (I've had unipolar depression for my entire life, with the occasional sort of manic or delusion-of-grandeur type episode)and I think you are very wise to pursue this route towards a better life. anyways, if you choose to check it out, i guess im just saying its safe, you will find no religious zealoutry or grandeuristic madness there. the buddha taught to (and how to) overcome obsessive attachment to things that bring pleasure and obsessive aversion to things that bring pain -- what else is "manic depression" aside from this? i think this is a very promising system for many types of mental health issues, esp. bipolar -- so if you want to, go ahead and pursue it! just be careful to keep your own manic delusions in check; buddhism can help to train yourself to do this as well
