I think that the story arc is, if taken literally, a person who frequently visits an elderly friend or possibly family member. The use of the first name suggests that it isn't family, although it could just be because it sounds better than 'grandma' or 'aunt Juliette'. In any case, they talk and share stories and enjoy each other's company but she has some sort of terminal illness or is simply ready to pass on and she eventually commits suicide, hence the note. The fact she fell 'asleep' suggests she poisoned herself in some way.
