"烦恼快离开" 的英文说法是 "worry be gone"。这个表达来源于英语俗语 "out of sight, out of mind"，意思是指当某事物不再显眼或脑海中时，它就会被人遗忘。例如：
When I put my worries in a drawer and close it, they seem to disappear. (当我把我的烦恼放进抽屉，然后关上它，它们似乎就消失了。)
If I keep busy, I don't have time to think about my problems. (如果我忙碌，我就没有时间去想我的问题。)
另外，"worry be gone" 还可以解读为 "拜拜烦恼" 或 "烦恼滚蛋" 的意思。例如：
Worry be gone and let's enjoy the party! (烦恼滚蛋，让我们享受派对吧！)
I'm tired of worrying all the time. Worry be gone! (我厌倦了一直担心。拜拜烦恼！)
