I'm a senior nursing student that will be graduating in May 2019. I have been renting a room from an older woman, 74 to be close to school and work. The last 2 years have been fine but her son just notified me she is in the early stages of Dementia Dx by her doc. They are asking me to help with her meds, chores, shopping and keep an eye on her. Besides school I work 40 hrs a week and honestly...I do not feel comfortable with the responsibility even in exchange for less rent. She also has 4 kids that live 20 minutes away, 2 of whom do not work. Any good responses as to how to say "No". I honestly don't want the legal responsibility and don't have time to care for anyone. I feel bad, though.
