Grief/Depression: You are probably having symptoms of Depression and fear of dying because of grief from the loss of your Father. It sounds like a psychological rather than a physical problem. But to be sure it would be good to have a physical exam with your Doctor. Then you could consult with a Clinical Psychologist who could help you with your grief and fears. Medication may offer additional help for you.
