I think we all have this struggle, regardless of whether we'd say it's with God or not. Faith - including but not limited to the big-f FAITH in the church way - is just about the last thing to rebound after the loss of a baby, I think.
Small-f faith - the general feeling that things are going to be okay - is so elusive. I'm still desperately seeking that... or at least a certain level of comfort with not knowing if anything will turn out the way we wish. Being able to shove doubt aside and be content despite having seen the swallowing void that may or may not await -- that must be one of many possible definitions of peace.
an expectation that things will go well -- this is unmet. Have to live with uncertainty. Faith does not eliminate uncertainty or guarantee against future loss.
