Thanks Pandora. I'm feeling quite a bit better tonight. Overall my trip went really well. I made it through the busy airports, taxi cab rides, busy cities and so on, with way less trouble than I thought I would have. My main issue was worrying that someone in the crowd had a gun and was going to start shooting, so I was checking people for weapons a lot (in my mind, not literally). It really helped though to play my Nintendo DS, wear my headphones and have my family there. Of course I crashed and had to rest in bed for a day after arriving at our destination but I was expecting that. I got through it, I even spent 4 days in New York City, totally unexpected! I'm confident that I can travel more in the future.
