Dear Ramesh, There will be some people in your life who play a pivotal role in bringing you up & shaping you to be the sensitive & beautiful person you are. It could be your parents, siblings, few relatives, few friends and this uncle of yours. He was very dear to you & has been there for you whenever you needed him. You have shared many precious moments with him, you carry few of his thoughts, his love & beliefs hence he is a part of you and still living through you however similarity ends there. He happened to have his own body which he alone fed, took care of & possessed. This one, with it's own ailments, he couldn't share with anyone and has gone away with his demise. He lived a great course of life in last 60 years. You were loved by him & he will stay with you as love & fond memories however he would never ever wish to haunt you or transfer his sickness to you, neither in his dreams nor after his death. You, my friend have interpreted your attachment with him wrongly and haunting him now by being affected in this way. He wouldn't want this. Go to church today, think about him & free him from all this so that he rests in peace. Do it till you let him go. Additionally follow things other doctor has suggested. You should not need any medication further. You are alright. Just let this realization sync and take care.
