A small event brings a big change in your mood.

"Menhera" is a Japanese slang term used to describe people with unstable mental health or emotional challenges. This 30-question quiz provides a thorough analysis and is suitable for both men and women. The test assesses your "menhera level" across five dimensions: mood swings, dependency, negative thinking, low self-esteem, and emotional expression.
“Menhera” is Japanese internet slang derived from “mental health.” It can describe emotional ups and downs or insecurity in relationships, but its meaning varies with context. It is not a medical diagnosis.

This area looks at changes in your mood in response to events and how you recover after feeling down. It is separate from whether you express those feelings outwardly.

This area looks at how much you rely on others for reassurance or decisions. The focus is on being affected by another person’s reactions, rather than simply caring about people.
Someone’s reaction makes you feel reassured or uncertain.
This area looks at anticipating negative outcomes or dwelling on setbacks. It focuses on what you expect to happen and how you make sense of an event.
A setback stays on your mind more than things that went well.
This area looks at difficulty recognizing your worth or strengths, and losing confidence when comparing yourself with others. Its focus is your view of yourself, rather than your view of events.
Comparing yourself with others makes your own strengths hard to see.
This area looks at feelings showing through your behavior and your tendency to communicate them to others. Strong expression does not necessarily mean strong internal mood swings.
You express your feelings strongly because you want to be understood.
Your overall score summarizes your answers, while the five individual scores show the breakdown. Looking at which areas stand out can help you make sense of the explanations.

Read your overall score and its accompanying explanation. The number summarizes your answers; it does not establish whether you have a mental health condition or how severe one might be.
Two people can have the same overall score but different individual scores. Read each explanation to see whether mood changes, a critical view of yourself, or another area stands out.
Think about the situations and people you had in mind when answering. This quiz does not assign a separate personality type based on combinations of scores.
There are no right or wrong answers. Choose what fits your current everyday experience, rather than your ideal self. People of any gender can take the quiz.
