So this story is a bit strange. This all starts with Nail clippers, and a bad day Which is too long to pun on here, so I'm gonna start with the clippers. We have 3 Nail clippers in our house. I'm 16, she's 14, btw. Anyway, I need these nail clippers and I've been looking for them for a week. Yesterday I need a Sharpie as mine dried out and as I open her drawer there they are. All 3 of them. I take all 3 and leave the room, enraged. I had asked her about their location a few times during the week and she kept telling me she had no Idea where they were.

I cool down a bit and after she gets home from school after her practice. I bring it up with her and ask why she didn't give me any and she started to cuss and shout about how I disrespected her privacy and how I shouldn't have taken any of the stuff in her room, while simultaneously telling me to go kill myself. So I thrust 1 clipper in her direction and tell her to get out of my face because she disrespected me. Later I can hear her going on Instagram and snapchat, calling her friends and telling them what an "Ugly little S**t" I am, how I don't deserve a life and all that. I walk into her room and ask why she's taking the piss out of me. She said that she wasn't and that I invaded her privacy again. She threatened to tell our parents about me being in her room, but I took her phone. After all the sh*t I took today, I couldn't take anymore. I think I go overboard and tell her she's a spoiled b*tch who's a waste of space on this world. After she grabbed her phone again and I leave the room, like five minutes after that She starts she tries to take me out of the room, but I'm mad at this point and take her phone out of her hands, and throw it out a window. She screamed at me and went to go get it. It was also snowing, so she took a while to get to the area where I threw it. 

She runs inside crying and runs straight into her room. It's fine, nothing happened to her phone, but I feel guilty about what happened. Am I the asshole for going overboard on a bad day and making my sister cry?
