Eugenia had allegedly not seen a doctor in 5 years, multiple attempts were made to talk to her about her condition in private before taking the decision to commit her. She also would not have been committed if she passed the assessment by the doctor who visited her, but he obviously saw how sick she was. Please suggest a different way to get someone into some kind of help for mental health when the person in question does not even believe they have a condition in the first place. Mental health is a shitty one. Getting involuntarily committed is awful, but sometimes it has to be done in order to save someone's life. When else would someone step in? How much longer do you wait for the person to help themselves when they already look so unwell? A person may kick and scream their heart out for you to leave them be, just like if you tried to stop someone jumping off a bridge, but do you just let them keep going because it's fucked up to force them into getting help they don't want?
Eugenia is still in a lot of denial about her condition and can't see why what her friends did was necessary- she doesn't believe she was so sick she needed to be forced into treatment. She likely did not see how borderline skeletal she was, as per the nature of anorexia & body dysmorphia. Many anorexic people literally see themselves as fat. 'Body Checks' are not just for vanity, the person is checking themselves out to see if they need to lose more weight. They see normal muscle on their body as fat that needs to go. Unfortunately it seems the rehab/treatment Eugenia went into was just to feed her up to a level where she wasn't going to die and not some kind of treatment program to offer her actual intense therapy and assistance long term (she says she isn't seeing a therapist at the moment because she doesn't need to, she saw one when she was sick and that was it). Anorexia is a life long condition, it's not gonna be something that just gets better and goes away and unless Eugenia accepts that she will continue to relapse.
Having friends ready to make that decision to step in is a lifesaver for people with severe mental health problems. If Eugenia was schizophrenic and not eating because of delusions, avoiding any help because she thought the doctors were gonna put chips in her brain, would it still be fucked up to trick her into getting sectioned? Because anorexia is just as much of a severe condition as schizophrenia is, and kills a lot more people (it has the highest mortality rate of all conditions for a reason). Yeah it's shit to see, but if no one else was going to help her then someone had to do something. We all saw how she deteriorated over time and none of her family were stepping in to help her get better, what her friends did was not only right but ballsy- it cost them the friendship in the end to save this girl's life and now she is relapsing and they can't do anything as they've been cut off. With all the people around her pandering to her, supporting her point of view that it was fucked up that her friends did what they did, will only encourage her to cut off more people.
