Suddenly caregiver for father has cut family members off in a three-page written letter! What do I do?

Trgal, we need more information. Like what were the caregiver's issues with the family members? Could the family been overwhelming the caregiver?

Is the caregiver a family member or a professional caregiver either from an Agency or an independent contractor?

Does Dad live in his home, or is he living in senior care?
