I can't decide if this is horrible or not that bad

I can't decide if this is horrible or not that bad

Context: Ever since my sister went through a traumatic experience 8 years ago (she was 20), she has been spiraling further downhill. She wasn't facing any other mental health issues besides depression and PTSD until she tried to kill herself. She overdosed on drugs and went brain dead for a few minutes before they brought her back. We were told she would never be able to speak again. And, after she recovered we started to notice her inability to form proper sentences, and she became delusional. For almost 4 years she honestly believed that I was part of the drug cartel and would not let me eat or travel around our parent's house on my own.

But, my sister is a fighter and she is incredibly smart and amazing and she DID learn to communicate again, and she even went back to school and started dating and taking medicine and she seemed like she was doing so well! She also seemed happy, which was so great to see. So, regardless of struggling with OCD, anxiety, ADHD and Bipolar Disorder, she was pushing through and remaining positive and strong!
But then, 3 years ago the doctor she was seeing said that she was doing so good that she could be taken off the medication. I got really nervous because, like anyone who has or knows someone with a mental illness, finding the right medication type and dosage is a grueling, painful process. But also, she was an adult and we couldn't tell her not to go off the medication, so we all hesitantly watched as she made the decision to remove medication from her life...

Immediately after going off her medicine she became delusional and very aggressive (this is what happened before she got on the medicine). She started beating my mom and saying that my dad raped me and we were dating (???). She was still living with my parents while this was happening and I was finishing my final year of school, so I couldn't be there to support her or them during these changes. I would frequently get calls saying she had called the police on my mom or dad, only for her to get in trouble for lying.

Fast forward to the present–
My sister is now 28. She lives at home with my parents and has been locking herself in her childhood bedroom because she is afraid of my parents (she believes they've assaulted her and are out to get her). She gets food by screaming at my mom through the door. She uses my mom, because my mom is the only one who will respond to the emotional and verbal abuse my sister puts her through. She never leaves the house and has severe OCD. She is paranoid of everything - trash, certain foods, cleaner... She is also bulimic and eats $50 worth of food PER DAY(!!). This has resulted in my mom being broke, and having no savings (she is 65 years old). My sister also works out 6+ hours a day, because she is petrified of being fat. She will come out of her room when everyone is asleep to throw her feces and vomit in the bathroom or kitchen sink. My mom will usually wake up at 5 am to clean the mess before she goes to work. My mom and sister are codependent, and it's scary to witness.

I realized the severity of the situation recently when I was visiting home. I did LOTS of research and found that the only option to get her help (because she won't take action herself) is to get a mental health warrant. For those of you who don't know what that is, it's basically a warrant that allows police to forcibly remove your loved one from the house in order to get him/her treated/evaluated for 48 hours.

To anyone reading this, I feel like it will come off like I am a horrible sister who is just trying to medicate and get someone "under control." However, I was/am very worried about my sister and my senior parents. I was worried if I didn't get help soon, someone was going to get hurt, or die. I still believe this is the case. Especially now, because...

...I didn't get the warrant. The judge I talked to said my situation didn't constitute a warrant. He then proceeded to say that this situation will only get worse as she gets older. It was very unhelpful. The way we deal with mental health in America is disgraceful. There is a lot more to this situation, of course, but to write it all out fully would require paragraphs and paragraphs of explanation.

More context:
I'm 25
My family lives in DFW area of Texas

And finally.... Does anyone have any advice? I feel so lost with this.

To those of you who took the time to read this, thank you so much.

TL;DR My sister has a mental illness that is causing her and my parents to live in unsafe conditions. I got scared and tried to get her forcibly removed from the home.

UPDATE: I wanted to write an update saying THANK YOU SO MUCH for all of the support and advice. I did not expect to get so many comments. I have genuinely taken all of your kind thoughts and suggestions into consideration. Another thing I wanted to say that I didn't write in my original post is: you are not alone. Mental illness is a huge part of American society, and many people struggle with things related to mental health (God knows I do!). If you are struggling, know that you are not alone, you are loved and it's okay to ask for help. Thank you again, Imgur community, y'all are great.
