心情无法形容英语

At this moment I can't find a word to discribe what I am trying to express.

I could not express my mood with words at the moment,这个也够正式了其实翻译是很多样性的，翻译除了你说的正式之外，最基本的是可读性。

Helpless,mood now really is unspeakable

At the very moment words fail to express my inner feelings.希望能帮助你

I am down. I am very depressed. I have got a bad mood. I feel blue. I am upset. I am frustrated.

I don't know how to describe my current feeling !
