EWL
From my point of view you have given the lady some fantastic opportunities se may have well been refused otherwise. From your account she seemed somewhat stable, even in the 5 years you have been dealing with her.
From dealing first hand with many mental health cases over the last few years, it is an area that is highly specialised, and given the brain activity is still a mystery in many ways, each person will react differently even if a number have similar diagnoses. Even medication is tailored. Most of the time there are many folks out there who lead normal, productive lives, but they are on medication just as if they were reliant on aspirin to prevent clots or drugs to control epilepsy. The body builds up tolerances to medication, changes in weather, conditions stress and exercise all play intergrated parts in the absorbtion and total amount of medication needed.
This ladys mental health professional may well have had her under control and happy for many years. Its just that something changed, and I would think, somewhat suddenly. It happens. Heart attack, gall stones and diabetes happen too.
She sounds as if she was one hell of an adventurer and EWL has assisted her in living a life many would have thought not possible. I sure as hell know a few of the patients that land on my tailgate would benefit from travelling, and developing confidence in their own abilities within the bounds of their medications. The are stuck in the system, reliant on it, panic easily, and sure as hell do not need institutionalising. (I do believe there are a number of cases that do require intensive, residential care, and some require fully secure facilities.) I get a feeling this lady wasnt one of them when she went of her adventure to China.
EWL, *raises glass* may many more adventurers pass through your portalsof your agency, and live life as it should be lived.
Best of luck with your traveller.......
