picklemepopcorn I am so sorry to hear about your dad.
Please protect yourself from the worst of your mum by planning ahead.
My dear mum, who was not at all like some described here, got dementia and my sister was musing if she could manage to look after mum at home. She could not, and I was able to say that to her, and relieve her of any guilt about it, as she could for me.
If you have no siblings to take the pressure off, or even worse, siblings who encourage you to do more than you can, please make sure you protect you and your family from your mum.
Can your mum live alone? Does she wish to after your dad is gone? It may be worth having these conversations while your dad is still alive, especially if he is kind and will look out for your interests, and your family.
How is your mum's physical and mental heath? Could she really live alone long term? It doesn't sound like it "I'm lucky in that I don't live very close, and that my DF looks after her."
For example it may give your mum some comfort to know she has discussed the future with your dad before he goes. He might even visit flats, retirement flats, bungalows etc or even care homes with her, for the future, if appropriate.
It took 5 years after my dad died for mum to move into a type of sheltered accommodation. But after that she took a nose dive and within a few years was ready for more care via a nursing home.
"I think you posted them a couple of months ago, Italian, which is where I find out about it!" I think it was last week, I only heard about it through someone on the other thread.
