question: Hi, I am asking this question for my brother. He is 16 years old and in 11th class. He was made to take medical side as he was not confident enough in maths. He changed from hindi medium lower profile school to much higher level school. His performance degraded day by day and in the finals he failed. Watching him clearly shows that he is low in confidence. He can't answer general questions properly and also he is unable to concentrate on anything. He remains irritated for the day and have some childish hobbies like playing video games and with small rubber balls etc. Do we need to take him to a doctor.
