I loved your story about the woman in the car. It happens to all of us, if all you see is the negative, and all you think is negative, all you get is negative.
I see that you have many positive thoughts going on, even though I know that those negatives can intrude and temporarily get you down.
I also agree w/whatdidido as far as your husband's moods and emotons swinging just like yours do. They are able to hide it, since they've started closing us out of their life.
Keep up the great work - thoughts and prayers for you and your little ones.
