With feelings of self-respect and self-worth (7)
I believe the answer is:
proudly
'with feelings of self-respect and self-worth' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for proudly that I've seen before include "Haughtily" , "With feelings of self-respect and self-worth" , "With high self-regard" , "With haughtiness" .)
