She doesn’t drive, refuses to sit in the car for extended periods of time and won’t fly. Shes on a ton of medication and sees doctors pretty regularly. I don’t know how to initiate this transition, where to move her to, or how to even get all of her doctor information if she won’t cooperate and doesn’t really know what she’s saying half of the time
Even IF you were her legal guardian it's not "easy" to get a physically uncooperative adult from Point A to Point B.
Do you even have PoA for her? If so, is it durable? Or, is your PoA authority active (because the criteria is met, meaning she has an official medical diagnosis of sufficient incapacity)?
If you don't have PoA or legal guardianship, then this is your first step.
More info on whether or not you have this would be helpful to give you the most appropriate guidance.
