questions

I just got through watching this movie and I had a couple questions.

Why did Sandy leave her kids four years ago?

How did she end up oweing places money? Hardware store, pharmacy.

I know she owes Sarah and her husband money becauise she used their phone to call her aunt. With attirney, I think you get charged later by them and she never paid the bill.
