annie - I do so hope that respite care materialises. I have some idea what caring can do, and however much we want to do everything, we have to recognise that we are all only human, and, as my DD says, "You cannot pour from an empty jug." Take the chance to fill your jug and do not feel guilty. You matter too and you are doing a great job, but you cannot do it if you are worn out.
Just back from ENT appointment - he poked his camera up my nose and gazed lovingly at my vocal chords while I squeaked and growled to order. He says they are not working properly - not meeting or the wrong bits meeting or something - anyway he is referring me to speech therapy. I wonder which bodily system will start packing up next!! Fun getting older isn't it?!
