When she got sick，not that she was really even my mom at the end.

当她病的时候，我甚至感觉她不再像是我的妈妈。

【分析】口语的特点是大量省略有关成分，但据上下文而不会引起歧义。本句not 实际上是I don’t think 的省略说法。补充完整后：

When she got sick，I don’t think that she was really even my mom at the end.

【翻译】当她生病的时候，我认为她甚至真的不是我妈妈了。

at the end，意为“最终是；结果是”。本句用了“结果是”之意，可以不翻译出来。
