Please help

My mother whenever she is mad pretty much accuses me of anything possible. I'm pretty sure she resents every second of my existence. And I'm to the point of not caring whether or not I even live anymore. She claims I always treat her like shit while she denies vehemently that's she abused me or my brother growing up. I'm contemplating driving myself to a psych ward and and admitting myself until I feel better. I don't know what to do. I just don't care if I live anymore because my mother thinks I'm such a fuck up and a failure.
