TW: Mentions of death

I am having really severe anxiety and panic attacks to the point where I feel like I’m going to die. I know that I will be fine but I can’t get my heart to stop beating out of my chest and can’t stop feeling like I can’t breathe. I have really bad health anxiety as well so when I have physical symptoms from anxiety it makes my anxiety 100x worse. I keep trying to distract myself but eventually it keeps coming back and I can’t seem to get relief for more than 15 minutes. Any advice helps.
