Dreams about searching for something, like tea in your case, often symbolize a quest for comfort or emotional nourishment. Tea is typically associated with warmth, relaxation, and social connection. Your feeling of hopelessness while searching may reflect a current situation in your life where you feel you lack comfort or support.

Finding the tea shop with your best friend signifies the joy of companionship and the relief that comes from finding what you need with the help of someone you trust. This part of the dream might suggest that support from friends can help you through difficult times.

Overall, this dream could indicate that even when you feel lost or hopeless, there is hope and joy to be found, especially when you lean on your relationships. It may be a reminder to seek out those connections and support systems in your waking life.
