do you think this is too intense for a story?

it's about two girls that hate eachother and get shiprwrecked on an island. one i'm also planning to kill off. this is the part where one of the girls fly off the baot. from an unexplained explosion. sry about grammer. tell me what you think. thanks.Instead of going to the spa that day I looked out at the sea. It was sparkling from the sun. I just walked around the ship exploring. I had eaten lunch but wasn’t very hungry so I only had a few pieces of fruit and a small glass of lemonade. I was leaning on the rail looking out into the sea when I heard the first scream. So shrill and hi pitched that you knew it wasn’t something small a girl was running crying screaming about fire and bombs in the ship. At first we thought she had just spent a little to much time in the sun but then we saw the crowd coming towards us fear in there eyes. then it all happened so fast there was a second of deadly quiet , a blast of burning hot air a flash of orange yellow light and then I was flying hi up in the sky zooming upwards so fast I couldn’t believe it. I was flying and then … I wasn’t I wasn’t flying I was falling and falling fast toward the waters I had taken a few swimming lessons but not much just enough if I was swooshed into the depend by accident. I didn’t know how to dive our any fancy stuff like that so I had to rely on discovery channel and other TV shows. I new that if I just let my self fall flat on my back or stomach it would hurt like getting a big carpet burn all over your body. I tried to bend but the air made it a little hard finally I was ready to hit the surface. my last thought before I hit the surface was thinking how calm I was not flailing around our just letting my self die I knew exactly what to do. Splash. I hit the water like an arrow shot like a pro. Once I had entered the water I put my arms out to slow me down because I didn’t want to go in to deep. I swam up to the surface the water burning my eyes so much I had to close them and swim blindly to the surface. When I broke through to the surface I looked for something to grab onto. And found a piece of wood I hung onto it. I looked around and saw no boat any where. Then I felt something hairy bump into me from behind I swam around kicking my feet to see what it was and saw that it was a human body. I didn’t need any clues to tell me if he was ok. I could tell by the colorless face the closed eyes the way they laid in the water. I thought I was going to be sick and then I realized that there were more all over in the water. And the sight was horrible and I did get sick. That was when I realized that my family had been in side when the ship blew up. The smell didn’t help it smelled like burning flesh. I was sick again when I was done I wiped my mouth and started to kick looking for my family. My cool mind set had dissolved away and now was a frantic chase. I new that Sam couldn’t swim and that my mom and dad would have a hard time keeping her a float. I called out my throat burning from swallowing a little bit of the water. Samantha dad mom were are you .as I swam closer to the clump of bodies and still smoldering wood. I screamed out over and over again listening to only the waves of the ocean which were starting to get heavier. I keep looking for about an hour. I find a bigger square shaped piece and sit on it. Then a big wave comes by and swoops me up and brings me under neat the water for a few minutes. I’m numb the possibilities swirling through my head. I don’t even close my eyes against the salty sting. I lay down in an awkward position on the board feeling the waves beneath me. My stomach growls and my throat is starting to dry. I’m wishing that I had had a bigger lunch than just some fruit and a small glass of lemonade. Some how I am able to wander off to sleep.
thanks.
