Why do you feel she is suicidal is it because of the things she says or is she clinically depressed in your opinion has she given up if she need in need of being her sister is something up you have value on that others and look on as a burden when people are are self destructive only too often Society tells us it is best to turn it back on them and give them tough love so they can figure it out themselves or that they will drag you down with them if you stick around to try to help them and I think that that is not the way to handle it communicate with her tell her that you're scared for her anybody else in your family or the world can either figure that out and see that you're trying to save a life or it's their loss for not seeing it humanities is important especially when does a blood relative we are all f***** up we are all flawed no matter what she did no matter what she's still doing don't give up on her.
