what else can i add to this story or replace

It was just like any other morning. It was hot and the sun was gleaming. I was at a water park with my friends. Fast forward 2 hours and we are getting ready to swim in the pool. It was our first time swimming. Splash. I slipped by accident, and before I knew it I was in the deep end, 6 feet. I couldn't get up. All I could see was leaves. I was in there for a good 4 minutes struggling to save my life. No one could swim towards me. My life flashed before my eyes. Seeing my sister all alone knotted my stomach. Seeing my mother and father mourn terrified me. I thought of how I would survive until I gave up. I became unconcious.
