It's all right, mBass. I understand even the realization that you don't believe anymore can be overwhelming.
As far as your family goes, if you think it will be nothing but grief and misunderstanding from them, then don't make them privy to your exploration of other beliefs. Maybe they can know in the future when you're better equipped to defend yourself and why you've chosen a different path.
Just relax and try to go with the flow (maybe easier said than done?) and don't try to understand everything all at once, or even at all. Just start discovering what different beliefs are out there. Start reading about the ones that interest you, could be here or an outside source. Take it all in, but one at a time. There's no rush.
Oh yes, and welcome!! I hope this place will help you in your time of confusion!
