我着急。

You can use it as a standalone sentence or add a reason. If you want to sound more natural, add a 很 (very) to make it 我很着急. You can also say what you are anxious about by adding 为 (for) or just the topic after the phrase. It’s short, punchy, and gets the point across immediately. Use it when the taxi is stuck in traffic. Use it when your friend hasn't texted back about important plans.

Use it when you are literally running late for a flight. Use it when you are waiting for exam results and can't sit still. It works great in a restaurant if your food is taking forever. Just don't be too rude to the waiter! It’s also perfect for telling a colleague that a project needs to move faster. It signals that the situation is now a priority for you.

Don't use this for deep, clinical anxiety or long-term depression. For that, Chinese speakers usually use 焦虑. Also, avoid using it if you are just 'excited' about something good. If you are 'anxious' to see a movie because you're excited, use 迫不及待 instead. 我着急 usually implies a bit of negative stress or pressure. Don't say it to your boss as a demand unless you have a very good reason!

In fast-paced Chinese cities like Shanghai or Beijing, everyone is 着急. There is a cultural concept called 'Kuai' (fast) that dominates daily life. Being 着急 is often seen as a sign that you care about your responsibilities. However, elders might tell you 别着急 (don't worry/hurry). This reflects a traditional value of maintaining 'calm' (冷静) under pressure. It’s a constant tug-of-war between modern speed and traditional composure.

The most common spin-off is 别着急 (bié zháojí), which means 'don't worry' or 'take your time.' You’ll hear this from shopkeepers, teachers, and moms. Another one is 急死了 (jí sǐ le), which literally means 'worried to death.' Use that when you are beyond stressed and heading toward a meltdown. If you are rushing someone else, you might just shout 快点，我着急！ (Faster, I'm in a hurry!).
