I think the fact she's found success on being the "struggling fat girl wanting a more accepting world" (sorry if that offended anyone) I doubt she's going to really do anything different. Even after moving out from her parent's place we still see her engaging in bad eating habits, not picking up after herself, etc etc. You are right, she has a lot of potential, given what she did prior to the show proves she has the ability. It's just a shame to see what's happened and what will most likely continue.
