"God is everything or he is nothing. What was our choice to be?"
That's our 2nd step proposition. When I find myself worried about anything I remind myself of what my choice is.
Gotta have faith that if I am doing what I should be doing to maintain spiritual fitness God will provide for me.
That being said,"Faith without works is dead." How much "work" are you invlved in? I find my worrying is usually directly proportionate with my lack of service work at any given time.
Hope things work out for you.
