I saw a similar thing with my daughter at the same age, and interpreted it like you have. Looking back, I think I was wrong.
Hindsight is a wonderful thing and I wish I could talk to my past-self knowing what I know now about how my daughter developed. Maybe your situation is totally different but maybe it isn’t and perhaps you’ll find some value in what I’d say to my former self.
The one sentence is this:
She’s probably not “lazy”, she’s probably a perfectionist who is scared of failing.
Unchecked, this is a dangerous thing for her mental health in long run. Her future may involve extreme exam anxiety and crippling emotional stress.
What do you do about it? Love her and demonstrate that failing at things and finding things tough is acceptable. Talk to her about it and demonstrate it. Take up a new hobby together, and let her see you struggle at it and still enjoy it anyway. Praise improvement and effort above above achievement. Constantly tell her her good qualities and improve her self esteem; most of all let her know you love her.
Inside her head, she’s being controlled by her emotional pain at not being able to do something as well as she hoped. Understand that and try to break through it with humour, love and understanding rather than criticising her lack of effort.
Best of luck and I wish I’d learned this lesson 8 years ago.
