Hello
It is good that you are concerned and willing to help your partner out.
Please be patient as this is a testing time for her. Even though she may disagree but you can start off by trying out couples counselling first and later on if needed see a psychiatrist.
COUNSELING helps everyone, disturbed or not.
Next Steps
Seek consult online or in person with a good psychotherapist
Health Tips
