Why is it difficult to explain mental exhaustion to others?

[Hazel]

Do people sometimes assume you are just tired or lazy when you are actually mentally overloaded? How do you usually explain what mental exhaustion feels like for you?

 

[Shree]

I think it’s hard because mental exhaustion isn’t visible. You can look fine on the outside but feel completely drained inside. Since there’s no clear physical signal, people often compare it to normal tiredness, which doesn’t really capture how heavy or slow everything feels mentally.
