这突然使我很紧张了，那次我真的觉得非常沮丧，因为我觉得我根本就不能保护我的财产并且还不知道这个人是谁。

That wound me up the most. I was quite depressed about it at that point, because I felt I couldn't protect my property and didn't know who this person was.

我觉得我不能控制自己的身体了，而且那种虚弱令我非常的沮丧和害怕。

I didn't feel I had control over my body, and that fragility was frustrating and even terrifying.

这几天我确实觉得非常沮丧。

I did feel so frustrated these days.
