There are two short poems by this name. Both are about Mary Shelley's reaction to the death of her son, William (see also To William Shelley in this database). Mary Shelley's depression is so intense that her husband feels as if she too has died. Her body is still there, but her real self has "gone down the dreary road / That leads to Sorrow's most obscure abode." Shelley knows he cannot follow her into depression for her own sake; he must be strong to pull her back.
