I am so sorry you are having such a trial. It does sound like stress, but that is difficult to know. Have you tried just giving yourself permission to do whatever is pleasant and fun. Personally, I like to put on a pair of head phones and just listen to someone read me a book. Generally, I fall asleep and have to start over again, but that is O.K. I have time. Do you like swimming, there is nothing more relaxing or water walking. It is great for mainting muscle strength too. An aqua areobics class can be great to. You meet some really great people, who can bring joy into your life, and we can use all the joy we can get. I did the aqua areobics for20 years and have never been sorry.
