Trapped in my Worst Novel

Protagonists, the most important characters in stories.
They're the ones that are supposed to save the world and be a symbol of hope for humanity, the ones that can defeat anything in their way if they want to, the ones whom the reader wants to win and succeed...
...Well atleast thats how à good heroic protagonist should be atleast.

I wrote 3 novels ever since I dropped out of college at 20 years old. My first novel was probably the worst novel to exist, bad characters, basic and repeated plot and a terribly unlikeable rude protagonist. Thankfully, the last 2 webnovels were a complete success!
I was planning to retire from writing when suddenly i got hit by a car and woke up as someone i didn't recognize at all, but the worst part was that the school this body attended was the exact same school where the plot of my first novel took place, how crazy, right?

Welp, i'm screwed huh? Being in the world with the dumbest and the most arrogant students ever isn't exactly a good thing to be in? Yes, yes, i'm in my own novel, but why couldn't i have entered one of my more successful novels instead?? How annoying...

I guess the only thing i could do now is try to stay as far away from the arrogant protagonists as possible, I am not trying to die today! But if only the soul of this body i'm currently possessing right now wasn't screaming at me non stop to "give their body back" as if I knew how to do that, and why is there a mini version of them sitting on my left shoulder while a mini version of how i looked in my past life is sitting on my right shoulder?? This doesn't make any sense...sigh.
