If you want to mislead others about your mental state, you can consider taking the following approaches, but be aware that doing so may have a negative impact on interpersonal relationships and personal mental health: 1. **Expressing optimism or negativity**: Amplifying your emotional expressions or deliberately showing emotions that are completely opposite to your actual feelings. For example, if you are depressed, you can act very happy, and vice versa. 2. **Selective communication**: The information you share with others can influence their perceptions. You can deliberately filter the information you want to convey and omit some important emotions or events to shape a specific impression. 3. **Using body language**: Body language can convey many emotions, and deliberately creating body language that does not match your actual feelings. For example, smiling or laughing with a blank look in your eyes. 4. **Keeping it secretive**: Deliberately not revealing too much personal information, leaving others with the impression that you are complex and elusive, and people misunderstand your true state. 5. **Emotional reactions**: Occasionally showing extreme emotions, let others think you are emotional and unstable, which will affect their judgment of your overall mental state. Although the above methods can influence others' perception of your mental state in the short term, in the long run, this approach may lead to misunderstandings and trust issues, affecting relationships with others. Instead of deliberately causing misunderstandings, it is better to seek understanding and support. Sometimes sharing your true feelings with others is more beneficial to mental health.
