The recognition of your failures in your own abilities is a wonderful, painful, point in your Spiritual walk. The Christian Church is full of repentant sinners, well maybe not full, but at least 15 percent.
Start church shopping and find one that is Bible based and that you are comfortable in. Get in the Bible and start reading about all the misfits that God uses in his plans, really it is a comedy about man learning about God. That sounded a bit irreverent, but God knows my heart.
Soli Deo Gloria,
