Hello man, im 20, i feel similar to you had one panic attack last january and something has changed inside me, i have been having
palpitations everyday since, and can always feel my
heart beating, i have had tests done which are clear, yet i still keep thinking in the back of my mind that there is something wrong with my heart, i am currently scraping my way through college even though my attention span feels like it has almost diminshed, have exams in 4 weeks and getting seriously freaked.
