How do Sangu Delle's words from his Ted Talk and the documentary "The Mask You Live In" reveal the ways Okonkwo or Nwoye "deal" or "mask" their problems in Chapter 8-11?

Okonkwo lives in a patriarchal world where hyper-masculinity is his only sense of identity. The speaker in the Ted Talk related his sense of shame when asked by a mental doctor if he would like councelling. Shame is also what Okonkwo felt when confronted with emotion or feelings like empathy, even towards his own son.
