It's really weird because it's clear she knows her existence is miserable. I don't think she realizes just how or why she's miserable due to the lack of normal human behaviors. My theory is she's 1 IQ point above being a legal retard, which is cruel and ironic since disability payments are the equivalent of extreme success to her.
She has a completely broken mechanism to cope with life and the current trajectory ONLY goes down.
No doubt she's got severe depression, but hers is one that could be successfully treated (to an extent) by being a "normal" human.
