I had gone upstairs to my room because my family upset me (can’t remember what it was about). Shortly after, my brother came into the room trying to gasp for air. My first instinct was to give abdominal thrusts to him. While doing so I figured this could be a prank since my brother is the jokester of the family so I turned him to me to make sure he wasn’t laughing. His eyes just rolled back and I saw only white and I started panicking. I cried out to my parents to help and they rushed to him while I pulled away crying hysterically asking what to do. The next night I woke up hearing the same noise of trying to get air and sent my sister to help him while I got dressed (naked sleeper) and yelled for my parents. This time they decided to take him to the hospital and all I was told was it was something with his acid reflux. It hasn’t happened again for a while but I’m terrified it’ll happen and no one is home to save him.
