Heads up this is going to get painful and cringe (and long).
I was definitely the nerdy (but not in the good grades kind) class weirdo.
My teachers always said that I had "a lot of potential", but even when giving my all I barely passed at Portuguese and History, and failed Gym miserably. Also struggled with Maths until I got a tutor. Tried getting tutors for the others two classes I was struggling with, but it didn't work... I only had "good" grades in Science, Physics and Chemistry, Arts and English.
I literally went form 5th to 8th grade hiding myself in the library instead of talking with my classmates. Not that I ever got along with them really.
The majority of the boys had gross humour or didn't talk with girls because "girls are nasty", the ones that were decent or mildly interesting avoided me because lord forbid a boy and a girl just be friends (legit lost some good friendships because of this)! The majority of girls were just in a completely different wavelength. "We are too mature for cartoons and such" or made fun of my looks.
So yeah basically they would spend all their time making fun off me directly or loudly talking bad about me literally behind my back and throwing bit of eraser at me.
It only got worse as we aged, even other class weirdos avoided me.
So when we all moved on into a school that had a library, I quickly created the habit of going into the library and staying there reading or playing games or watching movies.
The librarian literally called me a damned soul.
Two girls of my class approached me once and asked me if I had heard some rumors or if I could follow this girl they didn't like around because "well, no care enough about you to notice you even there or to care about what they say when you're nearby so..."
I only got out of that habit when I joined the gardening club, the bullying was taking a toll on my mental and physical health and I thought maybe gardening would be help out (I wanted to go to the archery club but my mother said that it was "to violent for a sweet little girl" like me) and I met these two students who liked anime like me.
We all later on reopened the school’s Japanese culture club, but it didn't go anywhere lol.
