So, there are two things that happened today between us. The first thing that happened was: She barraged into my bedroom and started telling me a stupid thing that happened on the show she was watching. Then, stole a notebook from my room knowing that I was going to chase her and scream at her. Then, blamed me that the dog started panicking and was trying to get me to take him to the vet, which I refused then smacked a plastic pitcher into my face spilling the contents out.
About an hour ago, my mom made her help me look something up. She asked me for the login to a site. I said the site wasn't the right site. Then, she was like fine I guess you don't want your help and started hitting me over it. Popping the lense out of my glasses and causing my face to hurt.
I am petrified to leave my bedroom because I am afraid that she'll just yell or hit me again, so I am just crying in my bedroom hoping I don't pee myself because I can't go to the bathroom.

Sounds like a bit of sibling rivalry. You two are teenagers, or so it seems? You just annoy and bug each other. You might not have control over her behaviour, but you can control how you react towards her behaviour. Locking yourself in your bedroom and not going to the bathroom doesn't solve anything. I'm not agreeing with her behaviour, it sounds pretty childish and petty to say the least. But for goodness sake, don't buy into her pettiness ... "chasing" her and "screaming" at her solves nothing.
