Having not read any of the afore-mentioned replies, I have to say that Hazel's mental resolve has impressed me, there's no getting past that.
For me, Hazel has a rock solid view of who & what she is.
She has had no real reason to adjust this - even accounting for the so-called "Daley incident" (not that I think she has, but some people have slated her for that).
She has taken the criticism from her so-called bestie Dan - which was surely extremely hard to hear, without any backchat. She moreover has endured the mostly non-verbal disillusionment/suspicion/distrust following the Daley Fiasco, and moved on from that.
Hazel may not be a favourite of mine, but her mental strength/resolve is not in question for me.
