I am certain and "in my spare time" working on the idea that "faith" and all that goes with sensing it, are stored in the brain and the area is affected when a traumatic event occurs. I, too, no longer sense God as I had before my injury.

Try a vision quest. Even a CD of drumming and/or flute music can help you do this. Meditate first just to help clear your mind; use a candle flame to focus if you need to. Then lie down, with the drumming, and allow yourself to go...to find...your own quest area in the netherworld. Many things can come to you, including a sense of the Great Spirit, while on a quest.

I wish you well.
