Consult a child psychiatrist.. Try to speak to ur child for once.. Multiple factors are to be taken into mind while dealing with a child.. Most important don't be abusive or assaultive towards the child.. Have some patience don't get frustrated towards the child..

Don’t reach to any conclusion about her.

Child mental health issues are a little more difficult to understand and they are not straight forward in many occassions. Definitely need more history to comment on the issue ... her concentration level,her teachers feedback as to why she was not able to study, ability to understand general things in life etc
