My mum is driving me mad.. she is 81 and housebound has the heating on all the time and all she ever says is that she is cold even with this hot weather we have been getting. She has wet washing everywhere about the house and won’t open windows. I am constantly telling her that she is causing dampness but she won’t listen. I suffer from Asthma and am now refusing to go into the house as it’s bad for my chest. I constantly argue with her as she makes stupid stories up all the time and moans about the poor Carers constantly. Do they ever change it’s like Groundhog Day?
The best thing you can do for yourself now is educate yourself on Alzheimer's/dementia, as it will help you better understand what your mom is going through, and make you a bit more understanding and patient with her. Like already mentioned, Teepa Snow has some great videos on YouTube, and the book The 36 Hour Day is another great resource.
I used to reference the movie Groundhog Day, a lot when I was caring for my husband, because yes, at times it seemed like I was reliving the same day over and over. Welcome to the world of caregiving and dementia.
Do some reading about dementia. It will help you deal with her. Remove the things that she is doing that might be kind of unsafe. Make the house safe for you to be in as well.
Take lots of deep breathes and change your expectations. You will be much happier!
An immediate, temporary solution is to remove all the wet washing supplies to a location she can't find them and hope she doesn't go out to purchase more. You can purchase a free-standing portable room air conditioning unit for your bedroom to cool and dry it. You and your "mum" are probably not in the States so if you can inform on where you live, others on this global site can give recommendations for what social and legal services may be available to you to get relief from her daily care and make future plans.
Watching Teepa Snow videos on YouTube helped me to learn and understand a lot about dementia/ALZ so that I could engage in better and less frustrating ways with my LOs. It helps me to have more patience with and compassion for them as they muddle through their disease.
