It's our first performance next week, so we're rehearsing frantically, and I've got behind with my work, but it's worth it.

下周是我们第一次演出，所以我们正在疯狂的排练，我的学业都耽误了，但是值得。

I don’t want to get behind with my work.

【get】我不想拖延工作。

It might sound a bit selfish, but I don't like getting behind with my coursework, and it was a bit of a relief to have a break from Lou's misery.

这听起来可能有点自私， 但我不喜欢我的课程作业落后，从卢的痛苦中解脱出来让我松了一口气。
