From my knowledge mental health treatment depends on what hospital you go to. If you walk into an ER and tell them your thoughts or plans of suicide and you need to be there to be safe they would most likely have you admitted to their psych ward. Of they don't have a psych ward they would send you to the nearest mental hospital. In my area there are a couple hospitals that do this. If I ever need an emergency room for mental health reasons I'm going to the hospital er that sends patients to the best mental hospital in my area vs the hospital that would send me to the not so great psych hospital.

Also if you ever do outpatient check out the area hospitals and what they have to offer for your specific mental condition. For example some are great at drug and alcohol situations while other hospitals are more/better suited for schizophrenia or depression. Try to find a program where you aren't mixed in with court ordered folks. You don't want to waist your time with people who are only there because they have to be vs. Because they want to be there.

Hope you get the help you need!
