what do i do

tw!!! i’m not going to be censoring any words or anything so i apologize i’m just panicking and can’t think properly right now. so about an hour and a half ago i took 2 gravol cause it helps me sleep but around 30 mins after i started feeling nauseous and since then it’s just gotten worse. i have a gurgling on my throat (im pretty sure it’s just air trying to escape or something but am not sure) and i feel nauseous and im panicking. this happens every once in a while so i know i should be fine and i know that panicking makes it worse but i literally cannot help it. i also have to get up for school in a few hours but im probably not going to be able to sleep for a while so i dont know what to do. if anybody has any advice or tricks to get rid of this feeling or anything at all really that would be very much appreciated
