At work Melanie cares for clients with developmental disabilities, then comes home to look after her 13-year-old son Matthew, who has been diagnosed with ADHD. Her marriage to Rick is rocky, which increases her stress level. Being so busy means that Melanie never eats until she is famished, then she devours whatever she can find. Her situation leaves her too tightly wound to sit down to dinner with her family, so instead she relies on high-calorie snacks and late night leftovers.
