Because you are an immediate family member (sister) you do have the right to "section" your sister to a treatment facility if you believe she is in danger of harming herself, or another person. The best way to prove she needs this help is to document her moods with dates, times, and direct quotes of things she has said to you or to others. Gather witnesses to her behavior and ask them if they will appear at court if necessary. While this behavior is, of course, painful and emotionally damaging to you and your family, your sister is clearly in need of some psychiatric help and manipulation is a symptom of many psychiatric disorders, such as bipolar disorder. If she is truly sick, then the treatment mandated by the courts will help her. If she is simply using manipulation to get her way, then perhaps a few days in a psychiatric institution or even just having the police and legal authorities involved will show her that this is NOT the way to get what she wants. Good luck from one who has been on your sister's side of the fence, and gotten well because I was loved by people who wouldn't put up with my behavior any longer!
Of course, the advice above does not apply if you are a minor. Your parents must be the ones to take responsibility for the situation.
Well, you could do a few things:
Don't let her pull your chain! Step out of the power struggle. Do what she doesn't expect, but don't feed into it.
There are national suicide hotlines you, she, or your parents can call for referrals and advice. They can help your family find a counselor for her.
I know you're worried about your parents' health, too. But they need to pick a course of action and agree on how they will handle it. YOU are not responsible to keep the peace in your home OR keep your sister or parents safe. Directly ask your parents to make a plan for how they handle it...so you can do the same thing. But your parents need to 'DO', hon, not you as the sister. You aren't responsible to fix the chaos that starts. You aren't responsible for your sister, whether she acts responsibly or irresponsibly. All you can do is step outside of the drama and chaos.
because she is suicidal
Introspection is the examination or observation of one's own mental and emotional processes. It involves reflecting on thoughts, feelings, and behaviors to gain self-awareness and insight into one's inner world.
kill herself
In Act IV, scene I of Romeo and Juliet, Juliet threatens to stab herself if Friar Lawrence does not help her.
She threatens to kill herself.
She threatens to kill herself, because life is no longer worth living without the love of her life.
This shouldn't be hard to do. Tell her "Mary is talking about killing herself." You've got to speak up and tell her.
She is being forced to marry a prince called Paris by her mother. She is in love with Romeo but they are in different houses and their love is forbidden. Eventually her dad tells her to die in the streets and she is basically suicidal. She pretends to be dead and threatens to kill herself if she doesn't get the potion to make her look dead. But Romeo does not know she is only pretending to die so he kills himself. Juliet then wakes up and stabs herself with a dagger. Plus, the only time she ever got out of the house is to go to church. So yah. Pretty good life, don't ya think!
The medical consensus is that masturbation is considered medically healthy, and psychologically normal. Even small infants indulge themselves.
Juliet is prepared to take her own life if Friar Lawrence does not help her avoid marrying Paris.
Let her go. She needs time to find herself. Perhaps so do you. If she is meant to be yours, in the future she will return when the time is right.
The exact quote of one of the times Juliet threatens to kill herself is at the end of Act 3, Scene 2 where she says: "Come cords; come, nurse; I'll to my wedding-bed; And death, not Romeo, take my maidenhead!"
