Whitewave, how wonderful about your mum. But you said it clearly 'she has everythingto live for' - and that is truly great. The reality though, is that is NOT the case for many in very old age (I know this womand was not very old- but she didnt' want to get there and find it is too late. Once you are too weak, too old, too infirm- and even more importantly, have dementia or Alzeheimers- that choice is no longer open to you).
For my mum, who truly lived 10 years of misery after an amazing life- blind, in a wheel-chair, totally dependent, and hugely disappointed with the behaviour of my brother) she didn't feel she had 'everything to live for'. my regular visits from abroad, and that of her grand-daughters in the UK and great-grandchildren, was lovely and much appreciated- but she couldn't read, couldn't play the piano, couldn't admire the countryside or the birds, her 2 best and wonderful friends had died, she was totally dependent- and hated it. She was in a great care home and very well looked after- but this is NOT what she wanted, and she truly wanted out.
Despite being a founder member of EXIT, she was stuck unable to ask for help, because it was against the rules of the OAP home, and because my dad, a Catholic, begged her not to. My guilt comes from NOT helping her- and not the other way round. Part of the reason we moved here was that I could take her home, where she could die in peace- but anyhow, dad would never have forgiven me. When she did die- having refused food and put her head to the wall (3 weeks before our move here!!) dad who was as fit as a fiddle at 96, died 3 months later. The Law has since been changed, and OAP homes are no longer allowed to refuse their residents to ask for help to die from EXIT. I was part of the campaign to get the Law changed.
