Hi Fiona,
Good Luck!
Relocating overseas and learning a new language, in addition to getting children settled is a huge task, not to be underestimated. You do not say which country you have moved to.
I would suggest you get yourself settled first, then thinking about contacting your new country's Physio body for information about practice set up, service provision etc. Also contact the CSP who may have useful/relevant info, also a list of mentors in that country. They did at one stage have a list of Ex pat CSP members in different countries who would assist new migrants in their quest for work/physio related advice etc.
It may be possible to contact other physio /practices/ hospitals for further info to give you some leads.
On a different tack, how about working with pilates initially to get your confidence back -it may lead to other physio opportunities.
Best wishes
Liz B.
