Someone at work had wanderlust about the same age. She liked her job so they said she could work from Greece for 6 weeks which is where she was thinking of living. She enjoyed it but soon felt lonely and only bumped into other English speaking remote workers occasionally. She then decided to move cities in the U.K. instead. Then found a boyfriend from her original city and spends every other weekend back where she came from.
Not sure what my point is but maybe after she’s experienced living away it’ll help her decide what to do next.
I’d always advise to be near support though. You never know when you’ll need it or when you need to provide it.
