He now lives with his step father Mr. Murdstone and his sister Miss Murdstone in his late father's mansion.
Mr. Murdstone tell him to work for his own living for his friend Mr. Quinion at London.

Behold me, on the morrow, in a much-worn little hat, with a black crape round it for my mother, a black jacket, and a pair of hard stiff corduroy trousers?which Miss Murdstone considered the best armour for the legs in that fight with the world which was now to come off?behold me so attired, and with my little worldly all before me in a small trunk, sitting, a lone lorn child (as Mrs. Gummidge might have said) in the post-chaise that was carrying Mr. Quinion to the London coach at Yarmouth!
[David Copperfield by Charles Dickens]
I'd like to know if "with my little worldly all," "sitting," and "a lone lorn child" modify "me."
Thank you in advance for your help.
