How does Douglas develop a sense of deep fear of water and what does he do to overcome it?

Explanation

Douglas was a young boy of ten or eleven years. He went to a swimming pool called Y.M.C.A pool to learn how to swim. One day he was thrown into deep water by a bully boy of about eighteen. He narrowly escaped death. It was a terrible experience for him. After this incident, he got scared of water. He also loved lakes and waterfalls. So he decided to overcome his fear of water. For this purpose, he hired an instructor. The instructor first taught him to stay in the water. Then he taught him to put his face under water and exhale, and to raise his nose and inhale. Next, he taught him how to kick with his legs. Thus piece by piece or bit by bit, he became a perfect swimmer. Then he went to several lakes and swam alone to overcome his fear of water. Thus maintaining his confidence and spirit he became free from his fear of water.
