I can't argue that Lindsay came from a messed up family. She was the bread winner and her parents seemed to be more interested in partying than raising their child. That said, it is always necessary to own one's problems. Tossing blame doesn't resolve anything. Fault aside, it is up to Lindsay alone to solve her problems, but that will never happen until she gains some self awareness. She sees herself as a victim.
I spend a lot of time with high school athletes, and whenever they feel they are losing due to alleged bad officiating or some other factor, I always tell them that it's impossible to be a victim and a champion at the same time. You have to choose a mindset. You have to control what you can (one's performance), and adjust for what you can't (officiating, weather, etc.).
Until Lindsay is able to see herself more objectively, she will never move forward in her life, let alone her career. It would also help for her to realize that the behavior she's displaying on this show won't make anyone rush to work with her.
