在中文中，"找到以前的自己" 可以用 "找回以前的自己" 或 "回忆起以前的自己" 来表达。在英文中，可以用 "find one's former self" 或 "recall one's former self" 来表达。
下面是一些英文例句和中文翻译：
She found her former self when she went back to her hometown after many years. (她回到家乡很多年后，找回了以前的自己。)
He struggled to recall his former self, but he couldn't quite remember who he used to be. (他努力回忆起以前的自己，但他不太记得自己过去是谁。)
来源: 这个表达是由 "find" 和 "former self" 组合而成的。"Find" 是一个动词，意思是 "发现"，"找到"。"Former self" 是一个名词短语，意思是 "过去的自己"。
