Urgent* Suicidal sister being discharged

Without going into detail, my sister attempted suicide and the hospital wanted her to be committed to inpatient but my sister and my parents talked them into her going home with them (she’s 36) and staying with them while she did outpatient short term therapy.

Well, it’s been a couple days @ my parents and she’s telling me they haven’t called her yet to schedule and she’s wanting to go back “home” to be with her bf who basically broke up with her and wanted her out of the house before this happened. He’s also an alcoholic. But she claims he wants her home and things change. I’m pleading with her not to leave my parents...
