Hello thanks for asking from HCM for your health related queries I can understand your concern. The symptoms like fear of death, worries about family, anticipatory anxiety that who will look after your family after death, pains in chest, fear etc are occurring due to severe anxiety most probably. Please dont ignore these symptoms and visit a psychiatrist for help. In severe anxiety medicines like SSRIs are mainstay of treatment. Medicines like Sertraline, Fluoxetine, Paroxetine etc are commonly used. These medicines will reduce unwanted repugnant thoughts and will help to decrease anticipatory anxiety. Please consult a psychiatrist for detailed evaluation and prescription of these drugs. Also try relaxation exercises, progressive muscle relaxation exercises, yoga to keep yourself relaxed and away from these thoughts. Thanks, Hope this helps you. Take care Dr. Seikhoo Bishnoi, Psychiatrist.
