求英语修改Three years time hurried by,the arrival of the graduati

Since I grew up,dance has always been with me.It has become the best part of my memory.During this time,my partner was the most important person to me.He gave the most help and support.Maybe he was the one who changed me.It was my first time to take part in a dance performance,I was only thirteen years old.After drawing lots,we were the second to go on stage.In backstage,I was very nervous and worried.My heart was pumping fast and there was butterflies in my stomach.It was then when my partner comforted me.Many pairs if dancer performed on stage,finally it was our turn.We danced carefully,worried about anything that might go wrong.Unexpected,at the end of the dance,because my heels were too high,I fell at the end of a pirouette.I was embarrassed as all the judges and teachers were watching us.When I reached backstage,tears broke out and I started to cry.I knew the score was going to low.I kept apologising to my partner and teacher.Especially to my partner,I felt guilty for letting him down.We practised hard for six months but due to my mistake,we cannot go to finals.When the scores were announced,we were eliminated because of our low score.
