1. Ask for help: communicate with your trusted friends or relatives and listen to their suggestions and support. If the problem is serious, you can consider asking for help from schools or units, counselors, teachers, HR or bosses, so that they can understand your situation and provide help.
2. Self-reflection: carefully review your actions and words, find out what may cause others' disgust or dissatisfaction, and consider how to improve. If you find that your behavior is impeccable, you can communicate with your classmates or colleagues in a more positive way and try to establish a better relationship.
3. Find new friends or colleagues: participate in campus or social activities, join interest groups or clubs, and find like-minded friends. At work, try to establish contact with other colleagues, look for similarities and intersections, and don't just entangle with isolated colleagues.
Finally, remember that being isolated is not your personal problem or your fault. You can take positive measures to solve this problem, but you should also pay attention to self-protection and don't let emotions and stress affect your health and psychology.
