I am suffering from panic disorder from the past few months. My doctor had prescribed me medicine but after 4-5 days my anxiety is back. I don't know what to do because my doctor is not available now and there is no way I can contact him. I am scared of these physical symptoms. I am having night terror because of which I can't sleep at night. I have to sleep around 3 am so I can fall into deep sleep and won't be interrupted by nightmares. What should i do?
