Fight with my mom

I go to gym everyday with my mom.
Today, After school is finished, I went to gym right away not to go to home.
I said my mom to bring my training wear, socks, and hair band.
But my mom doesn't bring it, so I can't attend GX program..
I waiited her fitness is over.
When we met, I'm so angry.
Because mom doesn't say sorry, and she just make sarcastic that I'm late.
But I'm not late.
After school is finished, I ran and I take taxi for not to late.
I understand she can't remember our promise, but I can't understand she doesnt feel sorry, and made me sarcastic.

I said "I'm not late." But my mom doesn't said sorry, and just said
"What are you sore at? Don't irritate"
I'm really angry about this.
I'm not irritated to her before I hear that she made me sarcastic.
It is way to go home by mom's car.
I really mad at, so I get out of the car and walk.
And now I'm not go to home. And I'm in a PC room.
I don't want to go to home.
But I have many reports, and I have to study.
I really don't know how can I do.
