我觉得筋疲力尽。

I feel all pooped out.

当时我总是筋疲力尽，有段时间还觉得做什么都没有希望。

I was always exhausted, and some days it all felt hopeless.

对我来说，它听起来就像是要同时干很多件事情，只不过全都完成得不怎么样，而且做完之后只觉得筋疲力尽，失败透顶。

To me it sounds like doing lots of things all at once, only doing them all very badly and feeling like an exhausted failure when it's over.
