In 2009 I was flying off to Cancun at the start of 1800 miles through eight different countries in Central America, six of which I'd never set foot in before. While preparing for the trip people warned me to not end up decapitated or kidnapped by drug cartels, and even though I knew the likelihood of something like that happening was remote at best, there were moments when I asked myself if this was really a good thing to be doing. But in reality, the apprehension wasn't really all that much different from any domestic tour I've done either. It really is about leaving one's comfort zone, which is almost always a good thing. When those feelings that you so aptly described descend on you, that's when you know you're really living. I feel sorry for people who have never experienced that. What usually follows is a life-changing experience, one that makes life truly worth living.

Have a great time.
