Hi
There is such a thing as 'religious addiction' where people will use religion just like alcohol or drugs to alter one's mood. Religion is ok but when it consumes your whole life and you can't think of anything else, then it can be destructive. Especially when loved ones are sucked into their religious addiction and have to think exactly like them. This brings up another theme of cults. As well as having church cults you can have 'cult-like families' where no disagreement or criticism is allowed. Everybody must think the same way and if you don't you are ostracised. Your family seems a bit like a cult and it seems you came off second best because you are open-minded. Food for thought.
Peace
