“你不值得”用英语怎么写？

You aren't worth it

You aren't worth it,either.

1) You are unworthy of ... Neither are you.
比如，You are unworthy of this honor, but I thank you.
2) You don't deserve it. Neither do you.
如果是不同语境，同意mola123所说。

You don't deserve it.
Neither do you.

如果是劝告别人你太傻了不应该去做某事，那是It is not worth doing so .

you do not deserve to.....
you too.
