give a stem/evidence of how Helen Keller's early childhood was filled with frustration and isolation due to her inability to communicate with those around her.

One piece of evidence of Helen Keller's early childhood being filled with frustration and isolation is found in her autobiography, "The Story of My Life." In the autobiography, Keller describes how she felt trapped and helpless as a young child because she was unable to communicate with others or understand the world around her. She writes about her struggles to express herself and her deep sense of loneliness and frustration at not being able to connect with those around her. This stem from her own writing serves as powerful evidence of the challenges she faced in her early years due to her communication barriers.
