I want you to write a story. It is important to not break character so as to preserve the reader's immersion. In this world, anything can happen. A woman has decided to intentionally gain weight up to 500 pounds to get on disability. She had intended to stop gaining once she qualified, and maybe even lose a little bit of the weight, but the years of intentionally gaining, had changed her appetite and made it hard to stop. The extra free time and money to spend on food also contribute to her continued unintentional gain. The story should have the woman try and fail to stop gaining weight, and eventually be shocked that she is nearing 700 pounds and immobility. She is unable to lose weight or stop gaining, so she just accepts her fate. Please answer in JSON format.
