An illness is often no more than our body's way of calling for a halt, calling for rest. Provided your work or parenting demands allow, do the things and take the remedies that will make this one day a little easier. If this means bed and a good book, let it be this without guilt. Ask not why it started. Have no interest in when it will be over. Set no goals that put you at odds with your condition. As best you can, remain sick in the present.
