This is very very important. Many people in these comments are arguing that there are choices that she could make to help her situation. That's true. But some kinds of conditions (lack of sleep, lack of time to yourself/to think, physical fatigue, fear of reprisal from most people--employers and colleagues--in your life) make choice itself into a limited resource. Could you technically decide to move/work out/fix whatever? Sure. Are you likely make that choice, be able to make that choice, or want to make that choice if your day-to-day is as depleting as what is described? No. Barring a few outliers, the ability to choose is suppressed for people in bad situations like this.
