Dorset Lady pointed out to me that I was on the wrong site but, nevertheless, provided me with some useful information, as did the those of you that replied as well. For that I thank you all and am able to say that I am much happier now.
However, as I am not suffering with the problems you all have, I have decided to take myself off the site. It only remains for me to thank you all, once again, for your kindness and to wish you all a Happy Christmas and a better 2018!!
