I just wanted to quickly add, how much I apprecieate all your input, and wise words on this thread. It's certainly a practical help, for me, to discuss this and to get third party perspectives etc. Even if I've not responded specifically to each and every comment, I have read and considered them all, and they have been most helpful.
Thank you.
Defo is a big learning experience for myself too. One thing I've noticed, is how I want to find a quick and immediate solition. I can't though, and for me, I need to accept that these kind of things take time. It's been a shock for us all, hopefully it's a shock that will shake things up and give my sister the impetus to make the changes she needs to make.
Jamie.
