What to do if my mother makes me want to kill myself?

I always wonder why I’m sad every day and now I know it’s because of my mother. It’s a range of things that I wouldn’t be able to explain in one post but she really pushes me to my wits end. I have no choice but to continue to live with her at least until I go back to campus in August and then I plan on moving to another state after graduation by any means.. but I just don’t know what to do at this moment
