I have the most horrible teacher ever?

So i have an art teacher called miss mclean.i've had her for 2 years, and the first year she was really nice to everyone and was really giggly and fun all the time.

on the first day of the second year she just turned into the grumpiest person ever! If someone was 2 minutes late because they were over the other side of the school she'd send them outside.one time my phone went off (because the button on the side of my iphone is broken somehow and turns itself on and off silent) and she gave me the dirtiest look ever. I said sorry i thought it was on silent, and she was like "it shouldnt even be on in school anyway" firstly who actually turns their phone off in school, seriously? And secondly the school head has said to us aslong as its on silent in classes then its fine.

we have started preparing for our exams, and i'm drawing perfume- to which she SUGGESTED i added a jewellery box and beads. So i brought in the jewellery box and the beads, after a while of drawing them i decided to change the jewellery box to something else, or just a different jewellery box, so that day i didn't draw it and just left it in my bag. She came round and snapped at me, wondering where it was saying WE decided on it, why haven't you listened to my instructions? I said i was going to change it and she made me bring something in after registration to show her or she'll choose something herself for me to draw, so because i was i was doing perfume i thought make up would be a good idea, when i showed her she started moaning at me because small things were harder to draw and honestly i actually found them quite easy to draw when i did them at home- easier than she made out anyway. And made me bring a jewelery box in.

so the next day i just thought id stick with the original jewellery box, so at that point in my composition, i had 2 bottles of perfume, a jewelerry box and beads. She came round the class and when she got to mine, she started to complain about the size of my jewellery box and beads.saying they were too small.

what do you think of this? And what should i do?

ps. This may sound like somethin trivial, but the way she says it she is all up in your face and patronising.someone even said to me after class "miss mclean bullies you like all the time"

I had huge problems with my teaches, it reached to the point where I started to really hate them (except my physics teacher) so I changed schools lol
Change is good.

I think yes she's grumpy but this is totally not a big deal and you should suck it up and deal with it. Also everyone should turn their phone off at school, I agree with her on that.

Just school, they have to keep control of the class or else they are mince.
