I don't answer the phone anymore but she fills up my mailbox with her messages. My mother is 90 years old and lives alone. I have told her I would have someone come sit with her in the afternoon but she refuses. I have asked her repeatedly to stop calling me when I am working. She'll get angry and say she'll never call me again. She calls for attention. I understand this but I can't pay attention to her. I have a high stress job and this is making my day worse.
