I am receiving an overall in-between vibe: brave but introverted; responsible (i.e. "weight of the world") but indecisive ("but i can't just pick between them and my beloved ones, that's like choosing to be killed or killing"); and cheerful but reserved.


With that said, the greatest characteristic I'm seeing is an adaptive response to the situation, and my vote goes to Thief.

Your occupational preferences, stage actress and psychologist (particularly with respect to analyzing others), lend themselves to this as well.
