Without the excerpt to read from, it's hard to know context. However, the other phrases don't seem to give a confident tone. "People staring" would create anxiety. "Smile to yourself" is very internal and doesn't project confidence. To "feel cheated" would be to feel hurt not confident. To have a "special bond" would be a private connection. So... "head held high" is the most confident phrase here.
