I do not believe that a belief is an absolute. I believe that an absolute, is something that can be proven, while a belief, cannot.
I do not consider myself to be troubled.
My requiring food, water, and oxygen to stay alive, (as I currently am) is an absolute.
This is the "logic" you are using:
You can't scientifically prove that others beside yourself have minds, therefore it isn't rational for you to believe that they aren't just pre-programmed robots.
But you'd rather bet on general empirical principles being a good way to place your bets. So would I, on matters of that kind.
When I'm thinking about "truth", I like to consider the words relationship with "troth", which beautiful word I will debase by saying something you "pledge your troth" to is kinda like something you'd bet on. And among things to bet on there are those worthy of your bet, and those unworthy.
But in general, the "Absolute" that you need oxygen requires some assumptions, and provides some joy about things entirely different from the "Absolute" that God loves you and wants you to be happy and good. The former merely requires that I stick around oxygen-rich environments. The latter suggests that I try things I never dreamed of, commit myself to things that make heroes go pale, and hope for things beyond my imagining. I find that exhilarating.
