Rainee, I hear you and believe you.
I’ve dealt with two mentally-ill family members. No one can know just how difficult this is until they experience it.
Unless the affected person is willing to admit and accept help, it’s almost impossible to intervene. You must essentially prove that the person is a danger in advance of the event, and our system doesn’t work pre-emptively.
My heart is with you. How worried you must be for your mother.
I have a good friend who has a older brother that is mentally ill and he lives on the street. He’s not at all a violent character though he is self destructive and he makes a mild nuisance of himself. He won’t voluntarily adhere to any treatment and as he’s never posed a threat he has never been committed for any length of time. The mother is an enabler, to this day the brother (late 40’s) will show up for a meal or to get warm. The father became a hyper authoritarian and my friend grew up under that father. (My friend never had a good relationship with his father, in large part because of the problems with his brother.). The father recently died and the mother is aging. It’s all very sad. My friend is not known for his patients though he is a great guy. He has almost no patients in dealing with his brother -far be it from me to judge that.
