Doubt

Do you ever have one of those days where you question everything?  Where nothing seems as sure as you once thought?  Where faith has taken a break?  Like:

What if I imagined God telling me to be a mother?

What if I am reading too much into situations that were merely coincidences?

 What if I've already told people - in my case, in a public blog - that I am called to be a mother, and I'm wrong?

What if I have stepped out in what I thought was faith only to find it to truly be thin air?

Yeah, I'm having one of those days.  Any brilliance to share?
