I agree totally, Catherine.
I understand you, @Love_Hope, it is difficult to face the idea of forcing treatment on a loved one. If she is not a danger, you can probably go to a court and file an ex-parte motion for evaluation and treatment because she cannot care for herself (is gravely disabled by the illness). Not leaving her apartment on her own for years, not communicating, not able to shop for food for herself, etc. are good enough reasons. You must fully explain her inabilities, don’t sugar coat. She can’t care for herself even while being cared for by her family. What would happen to her if they stopped caring for her, or providing her living space?
My daughter NEVER held resentment for being force hospitalized, it has happened 5 times now. She even viewed it as a sort of vacation from the abuse in my home… go figure. However, she has not yet voluntarily continued to take meds, even if they helped her, and returned to psychosis each time. I will see what happens this time.
However, I must warn you that getting your sister hospitalized the FIRST time is only the START of a LONG road of trying to keep her ON meds. One hospitalization probably will not result in her being med compliant for life, by statistic, hospitalization may need to be done over and over to find the right meds and to help her stay on them.
I am sorry to say that I don’t think you can do this from far away. Only if you lived nearby. And it seems her other siblings are not capable of continuing the struggle for her (to keep her on meds) once you leave again.
