Overthink, sleeping probl. Of allopathy!

My father has a misconception from last 25-30 year that he has facing some abnormal acrivies in his body like someone is pressing his shoulder, he choose to overthink about everything. While sleeping, someone is cursing him and then he awake thatsy he is not able to sleep properly causing the bad health of him and reluctant while talking to anybody. He is not able to concentrate on anything. This problem we are facing from last two months and last month i have got health checkup of him in which his ECG reports is not depict sound. Consulted a cardio, he was telling that due to anxiety some prob is seen in ECG. Another thing is my father dont prefer to take medicine as he feels that this is not a disease and it cant be diagnosed. We have got one psychologist in Alwar, who prescribed some sleeping pills and other medicine which i ll provide on demand. Not sure how should i deal with the situation as my father dont take medicine rather he prefer to take ayurveda instead of allopathy
