I can't find my child's good points. Even when told good things, it only sounds like consolation, and I can't take others' words at face value.

Being told good things but hearing only consolation—that's also a sign that you're facing this seriously and are tired. It isn't strange. In common: without margin in your heart, the good sides become hard to see. First, the parent's own rest and support are the foundation. "Good points" needn't be personality—small facts like "ate today" or "smiled" are enough. You don't have to accept others' words by force; jotting one down as a fact can take effect later. When low mood persists or it's hard, don't carry it alone—lean on your regular doctor, a consultation service, or a parents' group.
