Claim you've been diagnosed with a neurological disorder and/or seizures long in the past (infancy or years ago so records non-existant) or you've been having unsteady gait after TBI. Keep slipping and falling accidentally, if there's one thing that'll put the fear of Satan and God into any psych hospital its a patient liability lawsuits from slips and falls.
Was committed myself, was supposed to be for 39 days but after I started slipping and falling and landing on my head pretending everything was OK, just say I'm fine I'm fine, I just have post acute TBI and I'm not getting the advanced level of care that I need here so I'll be more careful. Do you have better socks?
I ws out the next day. In fact, the first patient out the next day before any other discharges. The doctors all of a sudden became friendly as soon as I said "well, my malpractic attorney told me to refuse X-Rays as he wants to see my chart first, but I can't remember his number"
Doctor shook my hand and I could see the fear in his eyes. Got a wheelchair escort out first thing in the morning, and loaded me into what appeared to be I got a free Uber ride home, guest they didn't want me slipping on their side walk and getting the fuck outa there without slip and fall misdianosed narcoleptic.
Be an actress, look confused ask what happend and AM I OKAY? Sorry, just need to walk more carefully. That way they know your not malignering.
