I've raised £3000 to help me to make my wife's time left as happy as possible

but she has been diagnosed with early onset DentiameIn early 2014 my wife started occasionally to ask me weird questions and use the wrong words when in conversation, I thought it was due to stress as I had been diagnosed with Cervical Myelopathy which later would result in myself being partially paralysed down the right side of my body.
As the years have passed my wife has become more child like with sudden mood swings and loss of recognition. Being partially paralysed I have been finding it hard to look after her and have tried to get some help, but unless I can get her to ask for help herself no one will help, as she has to admit she is unwell to get help, but she thinks everything is normal. Mental health is a bummer. I would not trade my wife for anything, I would just like to try to make the time she remembers me as happy times.
