new atheist need advice

[drfuzzy]

You sound like a younger me. (No offense intended - I'm middle-aged.) I was raised Pentecostal - my parents started out Southern Baptist and just kept moving more to the right wing.  (Or rather, more insane, take your pick.)  When the doubts started piling up, I did also look elsewhere for some type of spiritual meaning - Paganism, Buddhism.  But as lovely as those people were, there were still problems with the dogma. You just hit a spot where you CAN'T believe. 
    It kind of feels like burning down a house, then trying to decide what to build in its place.

Be very careful about telling people.  Consider their possible reactions first.  Drop hints, maybe . . . such as how the "Great Flood" not only tells a story of genocide, and a god who says that he screwed up (and then, after the flood, screws up in the very same way all over again) but how science has conclusively proven that such an event could never have happened.  But be careful.
