Paula,
You are so right about that queasy feeling. It always wakes me up to pay attention to what is going on, and usually, it is fear expressing itself as self-protection (self-absorption), or avoidance of the situation. When I am not being reactive, I actually try to use that feeling as a geiger counter for my next step forward...toward the fear and into the situation. When I have missed the moment and reacted, I try to go forward with my next move. When I follow that route, it usually is much less scary on the other side than I imagined.
