Although I didn't see the beautiful underwater scenery this time, and I didn't get to the underwater mailbox to send postcards as scheduled, this experience helped me overcome my fear of water for many years! Because I had the experience of drowning when I was a child, I never dared to let the sea water or stream water exceed my knees! At first, I let the sea water slowly from my ankles to my waist, and then the waves kept hitting my body, making me unstable. Until the coach carefully led me to a deeper place in the sea, I felt full of security, which was great~
