I’m having trouble calming down :( 

Long sorry short I got blood drawn to ease my health anxiety fears, it’s been 3 days and still no call about results which I’m guessing is good and means nothing abnormal.
But the waiting is making me have panic attacks I can’t stop thinking what if this what if that what if I won’t get to have a normal summer or junior year because of bad results I’m trying to ignore them but the so hard! My anxiety symptoms are through the roof I’m dizzy and just feel like I’m gonna have a panic attack at any moment :(
Does anyone have any advice to calm down while I wait?
