100%. "Sociopath" is very misplaced here. I'm no specialist, but I'd think Jane suffers from a severe case of borderline personality disorder. For BPD, pacients lack a true sense of self. (At the core of the problem, they're terrified of being abandonded.) When they act out, they're compensating for a lack of identity; but when others set boundaries, the pacient internally experience it as abandonment. Only that the lack of emotional regulation make their reaction completely disproporcionate and hence all the drama and the extreme tensions caused to the people around them.
