You'd be trading one horrific environment for another possibly equal one at a psych or depending on which. If you've been to a psych ward before, then you know the trauma that follows from being raped of your Liberty and literally being put in a prison restrictive lockdown facility where you're treated as a specimen and are only permitted one blanket, a pillow if you're lucky, and a writing utensil if you're lucky. In the US you have the right to wear your own clothes, the right to cancel the rating utensil and that's it. The one I was at did not even have pillows and the temperature was freezing nobody could leave their rooms because the hallways were freezing even more and you couldn't take your bed sheet to wrap it around yourself in the hallways due to policy. You're forced to go to group sessions better like kindergarten and you will definitely be categorized and stigmatized depending on your behavior and or social status. The psychiatrists that work in these wards are usually tall mad scientist sociopaths. Ask yourself, who would want to work in a zoo of screaming and kicking loonies on a state minimum physician's wage when they could use their psychiatry license in addiction medicine or some other more big dollar residency / vacancy?
When you're committed to a psychiatric facility you will have lost all of your human and civil rights and you'll be subjugated to the dominion authority of attending psychiatrists and the facility staff half of which want to get out of there and the other half that enjoy inflicting maximum emotional damage on patients.
The ideal patient of all is especially with good insurance - if you've got decent insurance, they will pathologize you and get an administrative law judge to have you committed before at least 6 months. That's that's 6 months of roaming around a building with only a shitty TV with sitcoms. You will serve most of your time walking the holes aimlessly roaming, staring at the ceiling in your room, maybe you'll have a window.
Maybe better the devil you know than the devil you don't. If you do go to a facility make sure it's a really high-end one, and bring clothing and books if your parents are not going to be involved in anything, oh and in the US cell phones / tablets insight words are banned. You will have no internet access at all, zero. You'll have a 1990s looking phone that you'll be able to periodically use if you can remember anyone's number to call that's tied to the wall so you can't strangulate yourself with.
