Think of the good day you had, singing with your boy, the fairly good night you had, your intelligent husband not taking you to the ER, your husband at work all day instead part of the day.
Do you have a notebook? Make it your friend. Write down the good things, the daily progress of your darling boy, how delighted he is with you, as are we, as you make progress yourself. You have a fine heart. Wish mine were half as good and I'm about 3 times as old as you.
