Hello thanks for asking from HCM You have feelings of hopelessness, poor sleep and panic attacks. Such symptoms are so severe that you can barely drive. I would advise you to consult a psychiatrist for treatment as these symptoms are causing significant impairment. Medicines like Propranolol, Etizolam, Clonazepam etc are commonly useful in severe panic attacks. SSRIs like Fluoxetine, Paroxetine, Sertraline etc help to reduce the frequency of attacks. Consult a psychiatrist for prescription of these drugs. Relaxation exercises, behaviour therapy, progressive muscle relaxation therapy, breathing therapy are other non medicinal methods of treatment with excellent results. Thanks, hope this helps you.
