Thanks everyone. Your replies are humbling.
I had always hoped that I was doing some good somewhere when I posted on the forum and I'm glad that so many of the people with whom I have interacted have seen my goodbye. I didn't want to make an unseemly splash by starting a separate thread.
Things are moving apace with me in that my wife has recently started 2 days a week at a Day Centre and I'm trying to move forward with a meds review for her and a carers assessment for me, along with a few other things. We were in a bad place when I stopped making regular posts a month ago but we are both happier and somewhat more hopeful now. I'm nearly back to my usual optimistic self. My wife just carries on in her usual way but it's great to be able to help her.
Once again, best wishes to all of you. It has been an honour to have given useful advice to some of you.
Pete
