Maybe the switch is because neither is fulfilling what it is you're looking for. Maybe it's time to be willing to consider some new conceptions and/or be willing to let go of some old ideas regarding what God is/isn't and try to do some new objective seeking?
I had a LOT of higher powers......so many it was a shame (as one of my buddies says it). At first it was a therapist, then I switched to a girlfriend and the therapist, then back to the therapist and AA as a whole, then just AA as a whole, then it was the steps/book. Now, I like to think it's God but there's a lot of evidence in my inventory to the contrary.
The God of my understanding is cool with all of that. He's also cool with religious beliefs of all kinds, using nature, using anything.......... I've found using myself/my intellect/my brain didn't work out so well as it tends to lead me away from anything being more important or smart then me. It also has led to stressed relationships......so I don't recommend that one.
