First of all, I'm sorry you're feeling this way. It's important to be honest with yourself and seek support. Even so, if you still want to appear good to outsiders, consider some of the following behaviors: 1. **Positive social media image**: Post smiling photos, travel experiences, or positive life events to show a positive life status. 2. **Positive words**: When talking to others, try to use positive and optimistic words, even when talking about difficulties, emphasize your confidence and ability to solve problems. 3. **Appearance care**: Maintain a neat and decent appearance, pay attention to your clothes and appearance, and make people feel that you are confident and optimistic about yourself. 4. **Entertainment and social activities**: Actively participate in various social activities or entertainment activities to show your love and participation in life. 5. **Helping others**: Participating in volunteering or helping others makes people feel that you are full of love and dedication. 6. **Setting and pursuing goals**: Talking about your goals and plans shows your vision and planning for the future. Although these behaviors may give others a positive impression, remember that it is important to pay attention to your inner needs. If you're feeling unhappy, it may help to talk to someone you trust or a professional. Your emotions and well-being also deserve attention.
