Causing others to worry about you is not a healthy or ideal way to interact. If you really feel that you need help or support, the best way is to express your feelings and needs directly. However, if you still want to understand behaviors that may cause concern to others, such as for academic research or writing, you can consider the following behaviors, but use them with caution: 1. **Mood swings**: Showing obvious changes in mood, such as suddenly becoming very sad or angry. 2. **Physical symptoms**: Frequent mention of physical discomfort, such as extreme fatigue, headaches, or stomachaches. 3. **Social withdrawal**: Reducing contact with others, becoming withdrawn, or unwilling to participate in social activities. 4. **Declining work or academic performance**: Obvious decline in work or study efficiency, often late or unfinished tasks. 5. **Loss of interest**: Loss of interest in activities that were previously interesting, showing a lack of motivation. 6. **Negative remarks**: Frequently making pessimistic or negative remarks, or self-deprecating. 7. **Seeking support**: Frequently seeking comfort or asking for advice from others, but it is difficult to reassure people. Remember that these behaviors can be misleading to others and yourself. Honest and open communication is a more effective way. It is also very important to seek professional psychological help when needed.
