Today i have been super anxious and im scared rn that I will have a heart attack or go into cardiac arrest or something. My chest area hurts a little
bit and it feels like I can’t breathe correctly. I had a heart palpitation or two today and those are also contributing to the anxiety. I’m 16 and have been to the ER about 3 times for panic attacks so idk of this is one of those or a serious issue and i’m scared.  Every time ive been there theyve said im fine but what if things have changed since the last time ive been there? I dont want to die.
