Hello! Please don't worry. Feeling nervous in crowds, sweating, or low confidence is common and can improve with small lifestyle changes and proper support. Try deep breathing before social situations, start with small conversations, maintain a regular sleep routine, drink enough water, eat balanced meals, and stay physically active with daily walks or exercise. If sleepiness or anxiety continues, consult a doctor, as it may be linked to stress, vitamin deficiency, or other health issues. A healthcare professional can guide you with the right treatment and support.
