英语翻译这几年来我改变了许多.以前我很高大,但现在没有了.不是我矮了,是因为别人长高了.以前我是开朗而且自信的,但我现在已经变成了一个沉默的男孩,而且有点自卑.尽量使用初中英语.我真的没分.不好意思

I have changed a lot these years.I was tall before , but not now.It doesn't mean that I become shorter but that others grow taller.What's more,in the past ,I was happy and confident.however,I am silent and a bit self-esteem now.
我在文章中加了几个简单连词，通顺一些，希望对你有帮助。

I have changed a lot in recent years. I used to be tall,but not anymore. It's not because that I have become shorter, it's because that someone else is taller. I used to be outgoing and confident, but I have now become silent, and somewhat inferior.

I have changed a lot these years.I used to be tall,but not any more since others have grown taller.I used to be outgoing and confident,but now silent and have a low self-esteem.除了自卑,尽量使用了初中...
