My roommate has been going through some psychological issues for the past couple of years, and lately she's been threatening to kill herself. I am really worried about her, she doesn't have any family so there isn't anybody for me to contact. I keep telling I will bring her to see a psychiatrist but she refuses to go. Next time when she threatens to kill herself can I call the police? Will they be able do something, can they legally take her somewhere to get help?
