There were many reasons for Helen Keller's embittered childhood. What were they and how were they overcome?

Helen suffered from a disease when she was nineteen months old. This took away her ability to see and hear. Her condition made her extremely dependant on her mother and she used a crude sign language to communicate her wants. Gradually, she realised that she was different from the other people. When she was unable to understand what others spoke, her frustration and anger grew. When her sister was born, Helen thought of her as an intruder who had taken her place in her mother’s life.

She became a very rude and an unruly child due to her inability to communicate.She led her life in a dark and silent world until Miss Sullivan came to enlighten her world. Sullivan was the embodiment of love, understanding, patience and and perserverance.
With the help of this gifted teacher, Helen was able to overcome all her shortcomings and was able to get an education too. Helen learnt to communicate with others with helps from Miss Sullivan who worked hard with her to gain confidence and not consider herself a burden.Helen learnt to see and hear with her fingers.Also, she learnt to read and write which enabled her not to feel defeated in life. Helen Keller and Anne sulivan dramtically changed the world's perception of people with disabilities.
