Yes, it sure can be...So far I have managed though, from time to time, come close, but always manage something before it's too late...I apparently am real good at talking my way out of a hospital stay - I really don't even know total how meany times I could see that's where it was headed, a few times even transport was on the way - but I reversed that, and ended up going home....
None of those times involved police though, and I can GUARANTEE it NEVER will - reason is, I have a standing thing - I refuse any hospital treatment of any kind as long as there is any sort of uninvited guest - so if a cop is present, or even waiting outside the building - I will not accept anything from anybody.
And it doesn't matter what type of hospital either, Psych or Medical, they leave or you don't treat period. Farther it absolutely must be the ones I wold normally use, or treatment refused there too...And even the ones of my choose - BETTER not share info with them under any condition or they are history - meaning if bought there, and they do leave just like I want and all that - they also will be prohibited from calling to tell them anything at all, including when they plan to discharge, or if I am being admitted - follow that, or even my own choose dose not touch anything.
