Hi Maya,
I haven't any personal experience of being allowed home with continuing care funding but I would think that it means that whatever care your mother needs, should now be paid for in full by the local Health Authority or Mental Health Authority.
Has she had a care plan made? Again I would think that the help will be very much related to a care plan which outlines the intensive care she needs. You may have to work with a Social Worker to arrange getting the carers in place but they should be fully paid for by these authorities and not from you or your mother's monies.
Sorry I can't be of much further help but I'm sure someone here will have had a similar experience.
Good luck with the care of mum, I know how hard it all is to cope with.
