So i had a massive anxiety attack about a week ago now and i think it was due to alcohol, im just not sure why it happened? Im wondering why my heart races, i than feel anxiety and think something bad is happening and i really dont know why. I went to emergency and they did a full scan on me and took my blood and did an EKG and said i was healthy as a horse and there is nothing wrong with  my heart but i seriously thought i was having a heart attack. I just dont know what to make of it all, and i drink maybe once a week if that? Can anyone help me out with this or has anyone had this problem before?
