Well, at te age of 79, with seven compression fractures and blood cancer, I find myself totally at the whim of my blind partner, cooking three meals a day and I've been told by a nurse I now need to cook four! It hurts so much to stand or to go backwards and forwards, up and down all day. My parter is a Type 1 diabetic so food is important, but he has a Libre2, which means the reader can give an alert at any time in the night while my partner sleeps oblivious and I have to deal with high or low blood sugar.
I don't get the time to rest that I really need. But if you do get the chance, Welshchrissy, remember that it is only that you have not had the habit of relaxing, and that is why you feel the guilt. Now, you have to build a new habit, and that takes time and a lot of self-talk. Your time is now, and it is your time and yours alone. Take it and your radio and your book, to your favourite spot and enjoy it as if you have been gifted that time.
