Answer:
The statement is true. Emily Dickison stayed for most of his life in his family's residence in Amherst, Massachusetts, and rarely left her house.
She dedicated most of her time to write poetry, and correspondence with a few friends, who rarely visited her (and Emily was not fond of visits either).
During the latter part of her life, she mostly stayed in her bedroom, probably also because she was suffering from an acute kidney disease that ended up killing her when she was 55 years old.
