求一首英文歌曲的歌曲名（中文名更好）

如果是乐谱的话，我弹了一下，感觉应该是这首歌：

歌词：
Big Big World-----Emilia

I'm a big big girl
in a big big world
It's not a big big thing
if you leave me
but I do do feel that
I too too will miss you much
miss you much...

I can see the first leaf falling
it's all yellow and nice
It's so very cold outside
like the way I'm feeling inside
I'm a big big girl
in a big big world
It's not a big big thing
if you leave me
but I do do feel that
I too too will
miss you much
miss you much...

Outside it's now raining
and tears are falling from my eyes
why did it
