Hi dear, I can understand your concern to your nephew. there are many reasons children deny in going for school, as it is an years problem in your cousin. I agree that medicines are advised from the doctor, but please try to find out the difficult the child is experiencing. was there any harassment, bullying or any kind of misbehavior might had occurred with him. or the child is scared of Academics i.e, it might be related to pattern of study, expectation of parents in which he feels that not capable enough. he requires empathetic support in which he can share his feelings openly, so that there wont be any judgement made on his behaviour. So please take him to the psychologist, through counselling sessions, he might come out of feeling of deny in going to school.

Is he going to the same school since 8th std!? Did u all check whether there was anything wrong in the school or something went wrong with some of his friends?! Was there any bulling or teasing..... Even if those things doesn't  happen now... could be the effect of those bad experiences. Please visit a psychologist  in ur city or at Orissa. He should be there personally wherever it is going to happen.

School refusal in children and adolescents are not uncommon and can happen because of various underlying reasons. Your nephew needs a comprehensive assessment to understand the cause. It can be due to anxiety or depression or behavioural problems related to some dysfunctions or manifestation of some fear, stress or even interpersonal issues with someone etc. I am not sure if medicine is the solution unless there is clear underlying mental health condition. Since he is an adolescent, he will benefit from psychological treatment like cognitive behavior therapy and counselling to enhance his insight into nature of problems and the impact. It has to be dealt with carefully with desensitisation techniques and empowerment without getting judgemental about his behavior. Team approach is advisable between parents, school teacher and therapist to ensure consistency and empathetic collaborative working with your nephew rather than being prescriptive about his behavior. Please consult a psychologist immediately. Regards
