Split Silver 164

I'm so annoyed right now.
I did this project for AP art that was a fucking collage or something retarded, I forgot to bring art to cut up (plus she didn't tell me what art I SHOULD bring to cut up) and so I got all these scraps from people. So I asked her opinion on my piece a million times so that I could get it to something decent, we do critiques and all I get is that the girl I drew into it feels a little out of place and her 'hand isn't desperate enough' which was the fucking point because she's trapped and wants to get out but feels bound to it and simultaneously doesn't want to get out. I get a lot more positive critique than a lot of people in the class and she gives me a fucking B-. I'm so fucking sick of this bullshit. I make the slightest mistake and she always drops me way below the grade I deserve. She's constantly sabotaging me. She tells me my people look like the fucking Sims (which I have never played, so I'm not really familiar with them), which I can only interpret that it's because they're stylized or digital or some bullshit - I don't really get the connection at all. Then, she's constantly trying to make us conform to her stupid obsession with modern art - which I believe has gotten to the point where people who can't draw use it as an excuse to call themselves an artist - and telling us that we're the next big creators of the world and we'll be coming up with the next big style (but she won't recognize any of my digital stuff as art).
I'm seriously trying so hard to just fucking please her so I can get a good grade (I'm going to do all my portfolio pieces outside of class, though) and she's fucking with me again!
She does this all the fucking time and I'm getting so sick of it.
My collage wasn't perfect, and I messed up the first day, but I just don't get at all how it would deserve a fucking B-. It was a B+.
She fucked up my GPA last semester that I worked so hard on, too, with my last project. She told me we were going to work on it in class on the last day and then changed her fucking mind and even though I got straight A's all semester (100%), somehow my grade ended up as an A-, even though the last project was a B.
She's a nice person, but I'm really sick of this bullshit. I don't understand my grade at all.
And I know it's not a horrible grade or anything, but she does little shit like this to me all the time to undermine me or some bullshit. I can't stand her anymore.
