Hello
@Hollyblue and firstly welcome to this friendly and supportive forum. There is a wealth of shared experience of dementia to be found here so I am glad you have found us.
I am sorry to read about your Mum. It is heartbreaking for sure to see a loved one slowly decline in front of your eyes. I do feel for you. I had the same with my dear Mum. It is good that you have arranged twice daily carer visits, along with your own regular visits.
All I would say is that you can only do your best - as I'm sure you are, in caring for her in her best interests. Please though do remember, with this disease, now is the best your Mum will be, and there might be a time to consider residential care at some point. A link may help for information:

You will always find support and understanding here from people that really do want to help. Do please also use this space to let off some steam or have a rant when you need to. Wishing you strength.
