I was studying for my exam and then I suddenly just feel weird. I had a little bit of ringing in my ears, then my body just felt so off… my heart rate is at 80. I have health anxiety so I’m so scared of getting a heart attack, but I think I’m stressed and feeling anxious cause I had 3 midterms day after day. How do I control myself?

I have meds to take as needed, not sure if I should use or if something else is wrong
