“难道我就这样被打败了吗？”翻译成英文该怎样？？？

感觉楼主是想强调“这样”这个词语来表示 被打败的方式令人匪夷所思或者无法接受。

How could it be this way I'm defeated in?

Is it real that I've been beaten like that?
Have I been beaten like that?

Could it be that I was defeated？

Is it that i've been defeated like this?

Could it be that I'm defeated this way?

表示“打败”用“defeat”较好。海明威的《老人与海》里就用了这个词：A man can be destroyed but not defeated.(一个人可以被毁灭，但不会被打败)。

用“could it be that” 表示“难道”的强烈感情。

How could I be defeated like this?
