Do you have a support group ? Church? Mental health ? People who are dealing with similar problem. A member of our family initially spent time in an assisted living and eventually had a studio appartment under control of mental health center. Check with your local offices for a social worker to help you.
People in the group had to divorce to get the financial help needed but still visit and involve individual in family activities (particularly the holidays)
Again talk to your local mental health group and get assigned a social worker to advise you
I’ve contacted NAMI but they’ve been no help so far. The have the standard cookie cut classes and seminars. She refuses to go to anything because she doesn’t feel she has a problem. She insists that I am the one with problems.
