Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Across the world, Every one has fear of death. No body wants to die. No body wants diseases. Still people are normal. Why?. Because they have so many other things to do or to think. You are a young person, I hope, though you have not given your age. Fear about death and health is called health anxiety. Counseling should cure you. Just consult a counselor. If you require more of my help in this aspect, Please post a direct question to me in this URL. http://goo.gl/aYW2pR. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques. Hope this answers your query. Available for further clarifications. Good luck.
