Struggling with Mental Health and Family Pressure

Hi 👋🏻 I have been struggling with mental health issues with 7 years and it’s very hard for me to work and keep a job. My grandmother (whom I live with) constantly puts me down about being almost 24 without a job and education. I tell her to please stop and she does it at least once a week. She goes on these depressing rants on how I need to do something with my life and asking me how it feels to have nothing. Please help on what to do. I don’t have the money to move out. Setting boundaries with her does nothing
