Have you ever felt so frustrated that you could scream at your computer, or so stressed that your brain felt like a blender? Thatâs when idioms for going crazy come in handy.
Idioms are expressions where the meaning isnât literal, and native speakers love using them to convey emotions in a colorful, memorable way.
Take Sarah, for instance. She was preparing a presentation, her cat jumped on the keyboard, the Wi-Fi went out, and her coffee spilled.
By the end of it, she told her friend: âI think Iâm losing my mind!â A simple phrase, but idioms allow you to express this feeling with more flavor: âIâm going bananas!â or âIâm at my witâs end.â
Learning these idioms helps you sound natural, humorous, and expressiveâwhether in daily conversation, writing, or even during exams like IELTS. Plus, they add personality to your speech.
