I'm a single mom of two daughters (18 who has end stage Cystic Fibrosis whose on hospice, and a 10 year old daughters). I'm an only child trying to take care of my girls, and my mom who has severe depression but refuses treatment. She's very stubborn and hard headed.
If your mother told you, she wants help. Really serious depression that intends self harm without intervention does NOT tell anyone. Unfortunately, I know this from personal experience in my family.
You report her to Adult Protective Services immediately. You tell authorities that she has severe depression and has told you that she intends self harm. Use those words. If she is under a professional's care for treatment of depression and you don't want to report her to authorities, tell the medical professional that she told you this. The professionals have an obligation to report it to authorities.
Not knowing the full backstory, it's hard to know if this is attention seeking or narcissism or a real depressive spiral. YOU have more than enough to handle with your daughters. Time to let the professionals take care of your mother. Holding good thoughts for you and your family in this terrible time.
I agree with Eye, if she's in AL, call the DON. If she's in Independent Living (which is what your profile says), I would alert the director of the facility to her suicide threat. You MUST take her seriously, but you don't have to go help her yourself. Please take care of yourself. And your children.
In my opinion your mom is telling you that she's going to kill herself because she wants you to do something about it. The proverbial cry for help. I don't mean to sound insensitive and I have a great deal of compassion for people struggling with depression and other mental illnesses but you have enough to deal with right now and I wonder if your mom is just trying to get some attention from you.
Not that you shouldn't take her threat seriously. You should. Your profile says she lives in ALF? Have you let the Director of Nursing know that your mom is suicidal? That your mom has told you that she plans on killing herself and then refuses treatment she's really kind of tied your hands.
You can't make your mom seek treatment for her depression and being just one person, a daughter, there's not a lot you do but try to be compassionate when your mom talks to you and continue to encourage her to seek help.
With your daughter on hospice and having a 10 year old at home and being a single mom who's also dealing with an elderly mother how are you handling all of that?
