My 8 year old boy is recently showing signs of palpitation and fast heart beat. I took him to the doctor and he said that my child has some imaginary fears. I sat with my child to counsel him and got to know that he s sad and embarrased because he not able to do well in sports ie. not even able to run faster and always comes last in the race and it bothers him a lot. I am very much worried. Please advise what I should do to help him.
