请用英语介绍一下你与三年前在外貌和性格方面的变化

I’m a middle school student. I've changed a lot in the plast three years.
Three years ago, I was short and thin. I used to be shy. My face used to turn red when i talked with others. In class, I used to be quiet and didn't ask and answer questions.
Now, I'm tall and strong. I'm more outgoing than I used to be . I 'm active in class and I can read text aloud before class.
I 've also made many friends. After class, I always communicate with my teachers and classmates. I think it is good to be a sunny girl.
