question: Last night I had a horrible panic attack and mistook it for a heart attack... by the time I got to the doctor it was gone, so I left. I am only 23 and I smoke cigarettes but have not picked one back up since yesterday afternoon because i was so scared. Should I forget it happened or go ahead and get it checked up? Im positive that it is mental because Ive had these episodes before, just not quite as bad or for as long. Ive been worried but I dont want to look stupid when I walk into the ER because I have no health insurance or a primary care physician.
