Paula,
First off let me say and I think I'm not alone here....you are probably the sanest person I have ever come across on any of the parkinson boards so hang in there!
It's meds or perhaps lack of them which are giving you psychotic episodes etc.
Not your fault, just remember that!
So are you in a rehab hospital for a fractured hip?
If so just do the exercises the physios give you and remember them or get a copy and quiz the occupational therapists for tricks they have up there sleeves regarding easier, safer ways of getting about.
You're probably with stroke pts because you're specifically in a neuro ward.
Is there any other parkys there?
They should and if they aren't possibly could let you self medicate with your anti parkinson meds.
If it really is a hole of a place and you aren't benefitting discharge yourself.
As long as you have someone to act as caregiver it should be doable.
Best wishes Paula,
Lee
