Hmm, it's been a while since I've read it. I don't remember getting that vibe from her, but of course she has had a lot of tough stuff in her life happen like her mom's suicide, her strained relationship with her dad, her exploitative relationship with Vadim, and people villainizing her for her politics, that kind of stuff - she doesn't shy away from talking about any of it. But I suppose it depends on your interpretation of what she says.
Most people I've heard about who have read the book really like it though and find Jane to be a very inspirational woman.
