a great change, especially causing or involving much difficulty, activity, or trouble

Yesterday's coup brought further upheaval to a country already struggling with famine. 昨天的军事政变使这个正在饥荒中挣扎的国家更加动荡不安。

I'm not sure it's worth the upheaval of moving to gain just a little more space. 我怀疑费这么大力气搬家就为了得到多一点空间是不是值得。
