Sorry to hear that.
You can go all your life to church and still be no closer to God. You can have Religion with out having God. At some point you have to step out in faith and trust my Lord and Saviour Jesus Christ. Not the teaching of a church. You must read and study the bible.
I'm not going to heaven because I'm faithful to church and all the things I've done. But because I trusted Christ.
As far as proof. Just look around.
I'll pray the Lord will show you his path for your life and that your faith may be restored.
