I had a panic attack 4 months back. Right after panic attack I felt dizzy and light-headedness. Next morning my face was numb. At that time I was confused whether it is a stroke or something else. It was only after I talk to some friends and a search on Internet that I realised it was a panic attack. After two months of that panic attack, I am having a constant thought of dying or say fear of dying. Now I can't enjoy hanging out with friends, working and going to Office because of that. I want to enjoy a normal life without this unpleasant thought. But I don't know how and what to do.
