The reason why people naturally relax when alone but become tense and anxious in front of others is fundamentally a matter of their perception of "a sense of belonging": when you consider yourself an inherent part of this environment, you will feel relaxed and at ease; once your subconscious perceives yourself as an "intruder," you will constantly self-monitor and worry about being judged, leading to nervousness and anxiety. True relaxation does not come from forced effort, but from inner self-affirmation—recognizing that you are qualified to exist in the present space. You are not here to be judged, but to breathe, express, and contribute value. Even simply existing is already enough.
