I Have Had a Panic Attack

My Worst Panic Attack Yet... It was about a year ago, and I was sitting in my room at my dad's house. Then it started. I couldn't breathe, and that inability to breathe only made me more anxious. I was overwhelmed by nausea, I remember thinking that I was going to puke... and then it all just went wrong. My body was trying to throw up as a result of the nausea, but I couldn't throw up because I couldn't even breathe. I ended up choking on my own vomit, convulsing on my bedroom floor. That was when my dad walked into the room. He stared at me for a few seconds, laughed, and left the room again. Sometimes I really wonder what is wrong with my old man.
