It is great that you are swimming... I try to do some exercise three to four times a week. Sometimes I have to forgo a week, or two... like this past couple weeks. it happens from time-to-time. Things flare-up.
I am married with no children. Although my husband is understanding, I know it gets on his nerves. We have been married for 29 years and I have been sick for about 21 or so years of our married life... It is hard on him and I try not to vent too often. A little normalcy goes along way in our household...
Don't worry about the cleaning. It will get done - sooner or later. You are not alone. Please remember that.
Take care,
Mere
