I've never lit a match with intent to start a fire;

Today my mother went on a tyrant rampage.
She came home and she started yelling about the mail just assuming that no one checked it because we were supposed to get Internet today.
There was some disc that was supposed to come in the mail.
But it didn't.

Then we were trying to hook it up and Jen was being all blah and having an attitude about it, even though she is the only one who even knows remotely how that stuff works.
My mother asked me to help by pushing this wire up through this hole in the back of out computer thing to see what it was connected to and I was trying but it was really far back there.
So my wonderful mother started making fun of me started making fun of me and telling me to hurry up but I couldn't because my arm wouldn't reach that far so she decided to yell at me.
She was all like "well I'll just do it myself like everything else around here" when she doesn't even do that much.
I do the most work around my house.
So she told Jen to hold the phone and listen for when someone picked up and Jen sighed and that just set her off and she started throwing things and yelling mainly at me for no apparent reason.
She told us we had to clean the living room dining room and our rooms and she was just going on and on about how I was lazy and how I always had an attitude when it wasn't even me.
I was crying most of the time while this was going on, and I was so mad, or upset or something but I was shaking with it whatever it was.

I was using all the effort in my body not to break down in front of her and not to yell and scream at her because I knew it would make the whole situation worse.
She was just putting words in my mouth and making me feel like shit until she left and didn't tell us where she was going.
As soon as her car pulled away I broke into hysterics until I threw up 3 times from crying and my dad came and got me.
