jealous mother??

So me and my dad have always been close, I go to him about everything. When I got my first period, first time I had sex etc. so whenever we're talking or he'll talk about me, my mother will snap, like start swearing or throwing shit, threatening me. We all live together and always have. (I'm 17 btw) I recently had to take a drug test cause she accused me of smoking drugs? Wtf? Jeeze I'm so sick of it, and I don't even know why? Like, does she hate me? What is her problem? Or am I the problem? Idk how to approach this. I started noticing it getting worse about a year ago and I just don't know what to do 😪😓
