Hi there,
First of all, please don't worry. It sounds like you are having quite a difficult time to juggle everything and I really feel for you. The situation with your mother is unfortunately far from unusual, but it can be resolved. Your mother, like most elderly people, wants to stay independent and she probably also would prefer to stay in her own home - her failure to notify you of her deterioration is a clear indication of this. By the sounds of it, there is no financial barrier? Care homes are often punishingly expensive and although you get the benefits of a certain amount of socialising, she will not be receiving one-on-one attention. The best option is to research a high end, top quality home care provider who supplies the following: personal care (where they can come in however many hours you and your mother want them to, and look after her personal hygiene, help her with medication, lift her in and out of bed etc), double-up calls (two carers come in at the same time, if need be), live in care (where you get 2 carers taking in turns living in with your mother and giving her their full attention), sleep in night and wake in nights (much what it sounds like - they either sleep in the house at night or they stay awake to watch her during the night, and help her into a different sleeping position so that she doesn't get sores), end of life care (again, highly trained and experienced staff who will look after her at the end of her life if she prefers to be at home rather than in a hospital) and also hospital-to-home service (so say if she goes into hospital and then gets sent home at some ungodly hour, the company can send someone out to the hospital to get her safely from the ward and into her own bed at home).
It is not a fact most of us want to consider, but you get what you pay for, in health care as with anything else. The cost for some of the services above might be slightly more than what a care home would cost, but the benefits to your mother and to your peace of mind are incalculable. I say might, as many care homes charge not just for the board, but for everything else on top, which you wouldn't get with a home care company.
I'm not sure what area your mother lives in but the two top quality providers of home care in the UK are Right at Home and Home Instead. You can go to their website to find out if they have an office in your mother's area and then go an visit them when you next see her - I would strongly advise a personal visit as you will get a good feel for the company and they will also be able to talk you through options and answer any questions you might have. They will NOT go into the hard sell - they are dedicated to provide help and person centred care first and foremost, and they will be happy to spend a lot of time with you even if you end up going with someone else. If you don't get a good vibe off the people, listen to your instincts, and also look at their office and see what clues you get - do they seem happy, smiling, are they welcoming? Also, all care providers (care homes, home care, hospitals, GPs etc) HAVE to be registered with the CQC (the Care Quality Commission) - you can search for any provider there. Look at their latest report and don't go with anyone who has a lesser rating than "Good" in all key areas (you will see what I mean when you go on their website!). Also, try the website of Homecare.co.uk - all providers who put pride in their services are on that site, with ratings from - and this is very important - actual service users. Read through their testimonials - what are they saying about the local office?
Anyway, I hope this helps - as you can tell, I could go on for ages about this so feel free to ask any questions you like. Also, one thing: you say your mum has suffered from UTIs - it's worth noting that a UTI can sometimes present with similar symptoms to dementia, so if your mother gets forgetful or confused, ask to have her tested and treated for a UTI!
Again, don't worry. Deep breaths - then do your research. There are lots of dedicated, professional, brilliant people out there who can turn this situation around for you and treat your mother with the dignity and respect she deserves, in her own home. Her quality of life will be much better and you can go back to being the daughter who visits and brings that extra ray of sunshine to her! Good luck!
