She’s been on a secret mission involving satellites: The woman I can’t help

What do you do when a family member with serious mental health issues won’t go to hospital?
When she lives overseas. When she is estranged from her former friends and family there. When she fills her purse with weapons so that she can intervene in potential conflicts so she can become a heroine?
And when the police are not necessarily the people one can trust “to protect and serve”.
This is the challenge I face.
