I FEEL SCARED AFTER CLOSING MY EYES WHEN

SO recently like a month back I was not with a  panic attack or seizure which I am not sure of but my symptoms match with anxiety attack , although during the attack I felt I was about fall , and felt that I was going crazy , I was barely able to stand , I was shivering, shaky etc. SO immediately the doctor told me to get a ct scan which came out to be normal, and my blood reports were normal too. Then the doctor told me don't worry and stuff and prescribed me divalex od 250 . Now after one month I feel ok but not as good as u used to feel . I don't weather these feelings are the side effects of the tablet. Honestly I can say that I am person with health anxiety. Recently I have started to exercise after a break of 6 months because I was diagnosed with epididymitis and due to which I had to stop weightlifting for a month but I ended up living it for 4 months . Before all this I used to workout regularly at least 5 days a week please help.
