Paranoia Support Group
Paranoia is a disturbed thought process characterized by excessive anxiety or fear, often to the point of irrationality and delusion. It is often associated with psychotic illnesses, sometimes schizophrenia, although attenuated features may be present in other primarily non-psychotic diagnoses, such as paranoid personality disorder and obsessive compulsive disorder.
She'll only be locked up if she s a danger to self or others and hospitals are disturbing abusive places and the medication awful
Instead of freaking out why not try to reassure her and have a good time and take her out places?
Maybe she forgets that she's eaten a cracker so she has evidence that the food is going missing in a way. I don't know if that kind of memory problem is a physical illness.
Why not lock the house up? It is frightening to be frail and old and On your own at night even if others are with you
Life doesn't treat mental health problems so good, I can see why she doesn't want to ask for help and why she thinks your against her. maybe you aren't so aware of what the world is really like?
Just take a few deep breaths... If you get to know many people you will find madness where ever you go... Most people are wounded. Keeping a confidence is how you gain trust.. Is it really so bad that you have to go against her wished and ask for help for her?
