Replying to What should I do, cause Im about to kill someone

I feel kindof childish complaining about this but I dont care cause Im about to explode.

First, My asshole A2 teacher wont let me go on 2 trips this week cause I have too many missing assignments and absenses. I have literally had 2 absenses this quarter and 3 missing assignments which is honestly not that much in my opinion.  So that pissed me off.  Then my asshole Marine Bio teacher who hates me for no reason at all, honestly, I did nothing.  everyone is talking and laughing about prom and other shit, even she is talking about bullshit with students.  I ask my friend for help, she turns and says "THIS IS INDIVIDUAL WORK, DO I HAVE TO GIVE YOU A ZERO!"  now, everone else is working in partners.  so I do it on my own for the remaining hour of class.  There is ten minutes left and I just pack up cause I finished one part of the lab and diddnt want to start somthing new.  She goes, "What do you think your doing just sitting there"  I say "I figured sinse class was almost over I would stop instead of starting somthing I wont be able to finish"  "You realize your participation is now going to make your grade tank"  she rolls to her computer to change my grade.

now I realize that most kids are like "oh my teacher is an asshole, and I think I am treated unfairly even though I dont deserve it"  I literally dont do anything but what I am suppose to do.  What do I do, talk to guidence? Write her a letter? principle?  Suggestions for anything besides killer her/

Notes:  Teacher treats me unfairly for no reason, what should I do?
