I'm sorry that you're having difficulty while being on vacation. It makes sense, you're away from your structured, familiar life. It's jarring to be uprooted sometimes.

If possible, I would try to find things to do that remind you of home, that are comforting wherever you go. If you like to read, or walk, or just take time to yourself, I would bask in your normal comforting activities so that it will distract you from being far away.

I hope you feel better!!
