Trying to cause unnecessary worry to others is inappropriate and may have a negative impact on the relationship. It is not recommended. But if you just want to understand the signs that may cause concern, the following may be interpreted by others as a cause for concern: 1. Frequently showing excessive fatigue and mental fatigue, such as always being listless, dull eyes, slow movements, etc. 2. Constantly complaining about various physical discomfort symptoms, even if there is no solid evidence, such as constantly complaining about headaches and stomachaches. 3. Continuously feeling low and depressed, always sighing and frowning, but not explaining the reason. 4. Suddenly losing interest and enthusiasm in activities that you normally participate in, and having a negative attitude. 5. Avoiding social activities and becoming withdrawn, which is in stark contrast to previous social habits. 6. Frequently showing anxious and uneasy expressions, such as fidgeting and increasing small movements, etc. However, it is still recommended to try to stay positive and healthy, and sincerely communicate with others about the real problems you encounter, rather than deliberately creating situations that make others worry.
