Advice?) I love my mother but it hurts me

I love my mom, but she always hurts me, whether it be physical or emotional, it gets so bad I threaten to call the police but, she ends up guilt tripping me, because I love her I really do, but I always end up hurt because of her, she tells me she loves me, and other days she will mock me for wanting to commit suicide, it all hurts so much I wish I could do something, I wish my family didn't see me as a dramatic crybaby, I just wanted everyone to be happy.
