Garden - Buy one of those blow up sx dolls, then phone the police from a call box and tell them there you have seen the owners burying a body in the garden, and they will be round and dig the whole garden over for you... Job sorted.
Father - I know what you are going through, had similar with my dad at his house. Unfortunately I was working nights at the time so it was a case of finish work, sort Dad out in the morning, go home for a couple of hours sleep, then back up to his house for lunch, then home again for another couple of hours, then back to his house for the evening meal and get him bedded down for the night. But it was the mornings I dreaded having to clean him up from what he had done during the night. Thankfully I had put a plastic cover over the mattress, so it was sheet washing every day. Then his mind went and I was re-named Bill, and he would sit looking out of the window and the kids playing in the school field became horses, then he would hold a conversation with the news reader on the tv. Eventually he went into hospital for what we guessed was the big 'C' and died there.
I cannot offer any advice except to just go with the flow, it will become frustrating, and in my case Social Services were a nightmare, waited in all day after organising adult style Pampers, and when the two drips from SS turned up all they had brought with them was 6 outer pants and not the liners, and when asked where they had been all day, the answer was shopping.... That is when I blew....
Solicitors - Scum of the earth, now I would rather deal with any problem myself and if it gets fannhouse, car, money in the bank the lot. ied up, then I know who to blame. Went to a solicitors when divorcing my first wife, the wife was 100% in the wrong, desertion, playing around etc etc.... The damn solicitor sold me completely down the drain and it was me she was supposed to be working for, lost everything, house in my name, car, money in the bank the lot, ended up sleeping on my mothers sofa for months.
So if your modelling has to take a back seat for a while, don't worry we will still be here and will I am sure have something to look at when you return.
Your health and the welfare of your life comes first for both of you.
