Art diploma bragging

HII!!! (omg I haven't logged here for 6 months.... BUT IT'S SO FUN TO BE BACK!!!) aaanyway basically I go to art school and i'm in my final year. For our final year we have to do a diploma in art and our major (mine is graphic design.) So with my major I had no real problems. I told my teacher that I want to make a comic about zombies and he instantly agreed (because he's such a nerd lol) but a real problem starts with my art diploma. So my teacher probably hates me or dislikes me at least because i've been fighting with him for the PAST YEAR about my art diploma and he STILL DIDN'T AGREE about a topic of the painting I want. My first initial idea came to my mind like 3 years ago. It was very personal and it was supposed to show my struggles with mental health and just how I felt. It was very veeery personal and meant a LOT to me, but when I first told my teacher about it he didn't allow me to make it saying that it's too graphic and the school won't allow me to have any nudity on my painting. (mind you a painting of a womans BOOBS was hung on the schools hallway for YEARS and when I told him about that he said that "well but this is differient!!!111) ughh. Anyway I was devastated but didn't give up and after summer break I told him about this idea again. Needless to say he didn't agree again. So I came up with another idea. A normal scene where a girl lays on her bed talking through her phone. My vision was that it would look like a scene from a 2000's teenage movie, something like mean girls or Jennifer's Body. AND HE HAD THE AUDACITY TO TELL ME THAT I CAN'T PAINT AND I WON'T DO IT??/? and he also had the audacity to write down that it will be a DRAWING not a painting when I told him VERY CLEARLY THAT I WANT TO PAINT IT WITH OILS. I was so furious I wen't to my supervising teacher to tell him about it, but he's kinda a pussy so he didn't do anything about it :// Later I showed him a photo I did when I was babysitting a puppy because I was so out of ideas AND THIS WAS WHAT HE LIKED??? (also I showed him my drawing I did for my mom's birthday when I drew her a portrait of David Tennant and Christopher Eccleston to show him how I handle portraits and humans in general AND HE TOLD ME TO MAKE A PORTRAIT FOR MY DIPLOMA OMGGGGGGG) I told him I don't want to do a portrait AND WE STARTED BASICALLY FIGHTING OVER IT in the end I told him no and just stood up and left. So later I took a photo of my second idea and then he randomly told me that he's gonna have to discuss it with the principal if i'm allowed to do this specific topic??? Guys i'm just so pissed. If he tells me I can't do this either i'm gonna cry SO BAD I'M SO TIRED AND DONE WITH THIS OMGGGG. Anyway that's it thanks for coming to my ted talk :3
