Depression, anxiety, and fear with difficulty in social situations are often due to stress, low confidence, and overthinking, affecting mood and behaviour. Build a simple routine, get proper sleep, stay active with light exercise, and practice slow breathing or relaxation daily to calm your mind. Start with small social steps, talk to trusted people, limit isolation, and avoid excess caffeine to reduce anxiety. Keep track of triggers and progress, and if it continues to affect daily life, consult a doctor to guide proper support and treatment.
