There is always a desire to do something but she never does anything with any conviction and just says stuff because it sounds great. The idea of getting your shit together is always better than actually getting your shit together. Im sure she cares, but not enough to actually do anything about it.
That's Amber's issue besides being the helpless hot girl stereotype (in her own mind shes attractive) is that she doesnt care enough to put in the work to get results. She will have to be broke, hospitalized and without a wipey or a becky type deal to enable her. Then and only then will she actually have to be pushed into doing the right things for herself.
