I have shortness of breaths. is it because of coffee?

i don't usually drink coffee but last night i went out with some friend an drank a mixture of coffee with four espresso shots appropriately named "the zombie" (i didn't sleep last night) a little after midnight, after i tossing and turning in bed, i experienced what i believe was an anxiety attack; i had shortness of breaths and my hands and legs were shaking. i was about to wake up my parents so they would take me to the hospital but after waling around my room for a couple of minutes i went back to normal. it happened twice after that and now i feel a little better but as i'm typing this i get small similar episodes. i'm worried! i don't wanna feel like that again. how do i get rid of the caffeine in my body? did this happen because of the caffeine intake? (that was my guess but i wasn't sure)
