Panic attacks return full throttle.

I had a minor panic attack in december but besides that I was free from it for about 6 months. Until now. I was just playing a game until all the thoughts started rushing into my head. My entire body was heating and my chest was becoming increasingly uncomfortable, I felt as if I could barely even gasp for air. I have calmed down now, but I am still shaking and will kind of get aftershocks from it. A heart attack is my worst fear despite turning just 15 not too long ago
