She might very well need psychiatric help but if she has an addictive disorder as well that requires rehabilitation. If she has a psychiatrist you should speak to them. If not the only way she can be hospitalized is if she is "dangerous to herself or others" but that is the last route. Its more important to speak to her doctor who might be prescribing her the pain medication, depending if she needs it. If she is taking it on her own without a prescription and doesn't need it that's far more of concern. Best to follow up with her doctors first. They may not be able to discuss her but they will note any information you inform them about and follow up.
She has changed from one clinic pain to the other until one they denied any prescription. My friend's father called her psychiatric office when was talking suicidal but guess what? They never call back. After calling the office several time the nurse toll us to call 911 next time, unbelievable. They main problem is that she won't listen to anyone and blame everyone for her problems (typical from her illness). WE have had to restrained her from her walking out the house at night when she had broke down in tears all of the sudden. Her ex-husband is other problem he is not a good person and is always giving her a hard time the girls. I believe this is getting to her. We have told her to ignore that @#$% , but she is way too sensitive.
