I had a similar experience to OP. But the catalyst for me was the Mountain Meadows Massacre[1] which I was completely oblivious to until my mid-20s. It was quite a shock to learn that the church (which I thought was "God's perfect organization") had such an ugly past. The most disturbing part was how much effort the church put to hide and scrub events like this from its members and the rest of the world.
That's very sad, for sure... but churches are only a bunch of people, trying to get closer to God. No matter how well any of them do so, they all ultimately will be failing at things all the time - anger, frustration, hate, etc.
Churches are not full of perfect people - it's the exact opposite. It's people who know they're not perfect, and understanding that, are still trying to understand life, and God.
All I'm saying is don't write off God - religion, sure.... Go for it, but God is not religion.
