Therapists are usually licensed to provide services only within the country, I highly doubt hers will agree to provide skype consults while your D is overseas. However, as you said, France’s health care system is great, you can get started early by doing a google search according to your criteria and reaching out to them. After your D signs a consent to release information , her therapist and doctor can share their notes and medical history, which will provide the drs in France a good starting point to treat her. I understand your concerns though and wish her the best of luck!
