Before my mum went into a care home, life was very bewildering for her.
She would do her shopping, without knowing what she needed. She would put her shopping away in odd places, and be sad and confused because she had no idea where things were. She would say "I am sure I bought cheese. Where is it?" Then she would spend hours looking for the cheese, without remembering where she had already looked. I would be called up on to help. Not because she so desperately needed cheese/toothpaste/cauliflower, but because she wanted reassurance that she was not going mad! The cheese/toothpaste would invariably be in her toiletry bag/linen cupboard/laundry basket.
She would cook dinner, clear away, have an after dinner nap, wake up, forget she had dinner/nap, and start making dinner again.... Or forget she had eaten, but remember cooking, and call me in tears because she could not find the dinner she just cooked. Somebody had come in and nicked her dinner! She would forget how to cook, and in the end make porridge every day saying "Its been so long since we had porridge, lets have porridge". I remember her last apple cake. She dumped the cake mix on an oven tray, with sliced apples in a heap. (no cake tin) and she was surprised at how it turned out, yet at the same time so proud of what she had made! She was beaming, she rang me to come and have cake. It was beyond sad to see a woman who could turn out the most magnificent baked creations beam in pride over a lump of dough with apple pieces on top.
Then she started getting up at 4 am, and without a concept of time, wanting to go visit her mum (dead 20 odd years)....
Or cook dinner. Go to bed with food on the stove.
Then she rang me in panic from holiday, because she wanted to go home. She did not understand why she was on holiday, and in such a terrible place. She did not like the cleaners and chamber maids, they were noisy and intrusive, there was a couple shagging in another room, and the view was terrible. She said she did not know where anything was in this hotel, and could not manage. Needless to say perhaps, she was in her own home, and had not traveled anywhere.
