We all have days where we feel completely worn out. While saying “I’m tired” is perfectly fine, sometimes you want to express just how exhausted you feel with more color and flair.
If you are looking to expand your vocabulary beyond basic sentences like “I need to go to bed,” here are 10 expressive ways to describe your fatigue.
Expressions for Low Energy
These phrases are perfect for when you feel like you have used up all your internal “fuel.”
- “I’m running on empty.”Think of a car with an empty gas tank that is still trying to drive. When you say this, it means your personal “energy tank” is empty, but you are still trying to keep going.
- “I’m running on fumes.”Similar to “running on empty,” this implies there is no actual fuel (energy) left; you are essentially running on the last remaining vapors of what you had.
- “I’m spent.”Just as you might say you have spent all your money, this means you have spent all your energy and have none left to give.
- “I’m drained.”A drain removes all the water from a sink. If you feel “drained,” it is as if all your energy has been completely removed.
Expressions for Deep Exhaustion
When you are beyond just a little tired and feel completely overwhelmed, try these:
- “I’m dead” or “I’m dead on my feet.”This is a common way to say you are so tired that you feel like you could collapse, yet you are still standing. You can also simply say, “I’m dead tired”.
- “I’m beat.”This implies you are so tired it feels as though you have been in a physical fight and were “beaten”.
- “I’m exhausted.”A strong, descriptive word for when you have worked too much and are feeling the full weight of that tiredness.
- “I can barely keep my eyes open.”This is a literal description of fatigue; your eyelids are naturally closing because your body is fighting to stay awake.
Expressions About Sleep
Use these when you are ready to call it a night.
- “I need to hit the sack.”This means “I need to go to bed”. Historically, this comes from the days when mattresses were large bags (sacks) filled with dry grass, which people would “hit” to make them fluffy and comfortable before sleeping.
- “I need some shut-eye.”A simple, idiomatic way to say, “I need to close my eyes and get some sleep”.
