This is just one among many questions and would like feedback but here is my situation:?

I was raised in a hard core fundamentalist belief. However i have strayed from that seing after searching, I do not find any proof to the teaching that God or Jesus alone is the creator of the universe,and to the other teachings on that aspect. What more, the hypocrisy involved and the looking down on other "non-believers" are unerving. I still believe in prayers, that there is a Great Spirit,and justice in the universe. My mother and I spend a great deal of talking, however when a situation is shared with me, and I say,"I will be praying for this or that person", I am made to feel that my prayers aren't worth anything because I am not a christian to their sight but a heathen. Isn't this just plain self righteousness on my mother's account? How do I relay myself to her that just because I do not believe in the bible doesn't mean i am lost?
