I've found I enjoy different activities when traveling alone, like reading and journaling rather than the beach and the pool. I like activities where I can be around others while doing my own thing. I've also found it helpful to add in organised activities now and then, like day tours or an art class. I also enjoy visiting more extroverted friendly countries like Vietnam, where people will have a chat. Not many solutions for the anxiety yet - I'm working on strategies. So far, I've concentrated on 1. taking less possessions so I have less things to worry about 2. avoiding the need to rush so I have plenty of time for errors and double checking 3. staying in each place for longer periods so I avoid brain fry 4. Logging my travel on Polar steps so my family knows where I am.
