HELP!

Last year,i went back to china.I had a great time with my friends.One day,we went to amusement park.We were so excited and happy.We played lots of games.The most interesting was roller coaster.

Firstly,i scaried because it seemed that it was dangerous.But my friends said they palyed so many times,it was safety.I said ok.escially,i never worried about it was dangerous,i just hate the feeling of dizzy.At that time,i knew i had to play it.second,all of us get in our seats.I felt bad.And then the machine started with a big "boom",i heard loud scream and felt dizzy.Our bodies turned left,turned right.My head went towards sky and ground.I felt my tharm was coming to my mouth.Suddenly,the machine stopped with a big boom again.unfortunately,i was headstanding, i heard only scream nothing at all.I just want to say :help,because i felt my blood flew towards head..One minute equal to a hour at that moment.It was miserable,i thought i was not married yet.Maybe today was my last day.When i was disappointed,my friends said everything would be fine.Finally,the machine restarted,and i went back to the earth.

After that i have never done that.I am cheerful i can live.That was the scariest event i have had,and i hope no more scary event happen in the future.
