<P> Johnson was unable to enjoy this success because Henry Thrale, the dear friend with whom he lived, died on 4 April 1781 . Life changed quickly for Johnson when Hester Thrale became romantically involved with the Italian singing teacher Gabriel Mario Piozzi, which forced Johnson to change his previous lifestyle . After returning home and then travelling for a short period, Johnson received word that his friend and tenant Robert Levet, had died on 17 January 1782 . Johnson was shocked by the death of Levet, who had resided at Johnson's London home since 1762 . Shortly afterwards Johnson caught a cold that developed into bronchitis and lasted for several months . His health was further complicated by "feeling forlorn and lonely" over Levet's death, and by the deaths of his friend Thomas Lawrence and his housekeeper Williams . </P> <P> Although he had recovered his health by August, he experienced emotional trauma when he was given word that Hester Thrale would sell the residence that Johnson shared with the family . What hurt Johnson most was the possibility that he would be left without her constant company . Months later, on 6 October 1782, Johnson attended church for the final time in his life, to say goodbye to his former residence and life . The walk to the church strained him, but he managed the journey unaccompanied . While there, he wrote a prayer for the Thrale family: </P> <P> To thy fatherly protection, O Lord, I commend this family . Bless, guide, and defend them, that they may pass through this world, as finally to enjoy in thy presence everlasting happiness, for Jesus Christ's sake . Amen . </P> <P> Hester Thrale did not completely abandon Johnson, and asked him to accompany the family on a trip to Brighton . He agreed, and was with them from 7 October until 20 November 1782 . On his return, his health began to fail, and he was left alone after Boswell's visit on 29 May 1783 . </P>
