请帮我看看我这英语说得对吗?谢谢

I would like to take back my resignation letter and cancel it.

貌似有点别就，应该是I want to

直接说,i want to take my resignation back. 不就行了?

可以。
同时提供你另外一个说法：I want to take my resignation letter back.

你那个英语说的是 请撤消我的辞职信。
如果在此背景下，没什么问题。
我本身做翻译的，没觉得有什么不妥。

I want to withdraw my resignation

辞职信,辞呈就是resignation
