>>2793939 (OP)I usually get anxieties around a week before my first day. The cause of my anxieties are mainly the fear of never going back to my home/seeing the people in my circle, etc.
When I first did my solo trip to South America years ago, I took a picture of a sunset. I sent it to my mom & it reminded me how I'm thousands of miles away from her, yet we both look at the same sun. I also remembered not finishing a game before the trip. During the trip, I always had a dreaded thought that is someone were to ever point a gun at me, I won't be able to see my mom and finish that game anymore. It's always the fear of dying that gives me the most travel anxiety.
It's weird that for me, the anxiety actually goes away when I arrive at my destination. I realize that I'm surrounded by humans where we're only separated by language but live completely normal & boring lives. I book hotels & private tours from reputable agencies since it acts as a safety net. While a perfect trip is never guaranteed, shit can happen, and that's part of traveling.
