My heart goes out to you Celebgran and I so completely understand why you asked, why you tried and why you are so saddened again. If a friend asked me for help I wouldn't hesitate to step up to the mark and do my best but, being in your situation for some years now, I know only too well that 'I'd rather not be involved' stance and how I've wished for those people to have to stand in my shoes. I do stand in your shoes and I understand the people who refuse to get involved, and who credit themselves with all sorts of virtuous reasons, but it doesn't make me like them any more.
Ooops, which is why my list of friends is very short these days.
