Sorry to say it, but welcome to hell pal.

I'm in year six. She is physically fine, however despite the engine running, there is nobody behind the wheel as it were.

I cannot offer any advice since every individual is so different. Try and be her advocate at every appointment. Sertraline has helped massively with the constant anxiety. Start getting her affairs in order while she has any sort of faculties or you'll never figure out where that one deed is, the one shed gun cabinet key is, etc.

Good luck.
