This is stupid........................…

My mom decided to take all of my electronics today because of a paper that is due anytime before Decemember 23. She said that she wanted a draft on Friday. I didn't know that she did. So i guessed that she wanted it on Sunday, since that makes the most logical sense. (Do paper over the weekend). I explained to her that the electronics are my stress reliever. She said that I am not old enough to have stress. I'm 17. Im thinking about what college to go to, what im going to study, avoiding negative pressure fromk peers, and what job i'll have to do for the rest of my life. I would have explained this to her, but as the coversation continued, she started to get closer and louder like if she were going to hit me. She use to hit me a lot when i was little. If she were to hit me, it wouldn't hurt, but I can't tell what would happen after that......So what should i do?
