I also think just like in a physical recovery, we get to eager and hope for too much too soon so when we have a bad day, it sends us over the edge.

When my father had knee surgery he was excited to play tennis again. He felt great. Then, the next time he played, it didn't go so well and their was some pain. He was despondant because his expectations were so high.

It won't turn around over night. Maybe keep a calendar with happy faces and sad faces....after a month, see if the number of happy faces as increased. Don't just look at the previous day, look at the overall.
