Just what exactly are you SUPPOSED to feel?

There is a new book coming out, detailing that Mother Teresa did not "feel" the presence of God or Jesus or whatever during the last 50 years of her life. Which suggests to me that she "felt" something for the first 35 years of her life. So, what the hell are you supposed to feel? In this country of >90% God fearing Christians, no one has ever told me that they "felt" anything. People have told me that they "believed", but no one has ever spoken to me about genuine "feelings". Does anyone out there "feel" the presence of God? What does he feel like? Is he tickly? Does his breath smell OK? Or is it kinda musty? Perhaps this explains why I am an athiest. I've never felt a damn thing. Well, I thought I did once, but it turned out to just be the cat...
