So why were you scared on the edge of the canyon? Were you concerned that you could not control your buoyancy and would fall into the abyss? Assuming that was it after the fact do you think that was reasonable at the time, and is it now based on what you know? No one will judge you (or should) for being hesitant going into a new situation. After all worrying is what keeps us out of trouble.
