It's important to remember that only a qualified mental health professional can diagnose any condition accurately.
Social anxiety disorder, also known as social phobia, is a mental health condition characterized by an intense fear of being judged, embarrassed, or humiliated in social situations. People with social anxiety may experience significant distress and avoidance of social interactions. Common situations that can trigger social anxiety include public speaking, meeting new people, attending parties or gatherings, or being the center of attention.
In your case, feeling nervous and anxious around people you know but not experiencing the same problem with unknown people could be related to social anxiety, but it's essential to consider other factors as well. For instance, it could be due to past experiences, the dynamics of the relationships with those you know, or specific triggers related to known individuals.
If you find that these feelings of nervousness and anxiety are significantly impacting your daily life, relationships, or overall well-being, it would be a good idea to reach out to a mental health professional. They can provide a proper evaluation and help you understand what might be causing these emotions and develop a suitable treatment plan if necessary. Therapy, counseling, and sometimes medication can be effective in managing social anxiety. Remember, seeking help is a sign of strength, and you don't have to go through it alone.
