Cách sử dụng
The expression "be at the end of your tether" means to be so frustrated or exhausted with a situation that you can no longer handle it. It's like the rope that you use to tie an animal to a post, and when it reaches the end of its length, it can't go any further. You might use this expression if you've been trying to solve a difficult problem for a long time, or if you're dealing with a frustrating person or situation that you can't seem to control or fix. It's important to recognize when you're at the end of your tether, and to take a break or ask for help before you become completely overwhelmed.
