Hannah is a depressed ESFJ.
Unhealthy Fe's are the ones who want to make others feel anguish over their loss, who would go out of their way to unleash a torrent of purely shared emotions on a tape and force others to listen to them. Who would use threats, who would get others active in "we" behavior (by turning them against her abusers, especially the boy whose window they kept breaking), and who would want to make them feel everything she also felt, each step along the way. The fact that she IS Fe is why it WORKS. She knows exactly how to do it.
And she refuses to take personal responsibility for any of her own actions or choices, while she's doing it.
By contrast, Fi's tend to self-blame. They will get so wrapped up in "woe is me," they literally think of no one else.
A depressive Fe will never look at oneself first; they will blame everyone else. Fe-doms, in particular, have an entirely external focus. Immature Fe-doms blame the object, the person, instead of themselves, whenever something goes wrong. It's not "Damn it, why can I never get this toaster to work?" (user error / I'm a idiot), it is, "What idiot invented this toaster?!" (obviously, the reason I can't get it to work is because SOMEONE ELSE designed a stupid toaster!). It's not, "I wish I were better at communicating with this other person, I always seem to say the wrong thing and set them off and then we have an argument," it's "I don't know what their problem is, they drive me CRAZY" (it's their fault I get upset and yell at them all the time).
Obviously, healthy Fe-doms don't do this, but you can always tell an unhealthy one by the sheer amount of "not my fault" that goes on with poor Fe.
I feel bad for Hannah. Her decision was awful. But I don't think a Fi user would ever propagate the idea that their own personal choice... is someone else's fault.
