I'm lonely only when I am overtired, when I have worked too long without a break, when from the time being I feel empty and need filling up.

只有在我过度劳累的时候，在我长时间不断工作的时侯，在我感到内心空虚，需要充实的时候，我才会感到寂寞。

It was only when I'd dissect the evening with friends that I would again feel empowered and fun instead of lonely, awkward and panicked.

于是我晚上不再和朋友们泡在一起，我感到重获自由和乐趣，不再觉得孤单，笨拙和恐慌。

I'm lonely only when I am overtired, when I have worked too long without a break, when for the time being I feel empty and need filling up.

只有在过度劳累时，我才会感到孤独，心也像被掏空了一般。
