The narrator's attitude in this passage seems quiet despondent and hopeless. He's definitely embarassed by the uniform he has to wear and is expressing clear frustration with both the situation and himself.
The 3 phrases that showcase these emotions better would be:
"Man oh man do you need guts to get on public transportation with it".
"I could keep wearing it if I hopped on with a group of Hidaya students because I wouldn't feel so exposed".
"There was no way I had the courage to go he distance alone with it".
Hope this helped!
