Feeling lonely, difficult to integrate into social occasions, and encountering difficulties in communication will really make people feel depressed. First of all, it should be clear that everyone has his own advantages and specialties, and these do not necessarily depend on social skills. In the face of social difficulties, you can consider the following suggestions:

1. Find the same hobbies: Try to participate in some activities that interest you, so that it is easier to find people with similar hobbies and establish the same topic.

2. Social skills training: You can take some social skills training courses to improve your self-confidence and expression ability in social situations through study and practice.

3. Seek support: If you feel psychological pressure, you can consider consulting a mental health professional who can provide guidance and support.

4. Gradually accumulate experience: Social skills can be gradually improved through experience. Gradually start a dialogue in the group and gradually improve the sense of participation.

5. Self-affirmation: Learn to appreciate your own advantages. Everyone has their own uniqueness, so you don't have to care too much about other people's opinions.

6. Set small goals: Start with small goals, gradually challenge social occasions, and make yourself more accustomed to and adapt to the social environment.

Remember, growth and change are a gradual process. The important thing is to accept yourself, try to discover and develop your own advantages, and find people who can understand and support you.
