While I have some strong opinions on mental hospitals, if you're treated this fucking badly there's information you're not disclosing, as per usual with redditards who never reveal the full story and circlejerk victimhood. Institutionalized adults who go against their will are legally cleared to be a definite danger to either themselves or others, and your case has to be pretty damn severe to get to that point. The government doesn't just lock up every single "neurodivergent" person on the basis of being "neurodivergent."
"Prisoners in jail are treated better" is such a mind numbingly ignorant take that could only be formed by an unironic coddled autist who never had to deal with any real hardship. The fact they don't think jails should exist tells you everything you need. Serial murderer and rapist? No don't get them off the street, it violates their privacy!
