Does anyone know how to get an adult child (29) taken to a hospital when having major episodes with bipolar an?

The behavior is so scarry and all she does is scream and yell about everything for the past 6 months and lately it has gotten so out of control, i worry about her safety as well as mine. she is very abusive and does not want to be interrupted, or not listened to. All she does is talk talk talk and goes on and on! it has made me almost feel paralized and unable to do what I use to and loose enthusiasm. I also have her boyfriend that stays here at times, and all they do is fight. she is so inflexable, and it not right how she and him are creating problems. Neighbpors have called police at times, but when they get here, she knows how to act as she is okay but was not happy with boyfriend. I am her mother and it is hard to deal with this and is getting the best of me. what does one do to get a person or duaghter the help they need. It never happens, and when it did about 3 months ago she was only in hospital for 3 1/2 days, and she did this to get extension on community service hours she did not complete. Such negativity and hard to navigate, i am feeling no hope, does anyone know of any suggestions. she goes to mental health, and has been on different meds over years. right now she has taken resoiridone ca??shot that she gets every two weeks and has a psychiatrist and case worker who are helpful, but they are for her and it is confidential so it is hard for me to be able to communicate the problems. It is out of control and something had got to change and I just don't see how it will, because I try all I know in Bay Area. she has 2 insurances and that is not a prolbem, it is just she doesn't think she needs help, it is what everyone else makes her do! this is all she will say and not allow another to differ from her or look out, it is ridiculous and has gone on way too long. Hlp!
