My school experience was more of a chronology of daily occurrences which were discriminatory towards me, due to my appearance. However, there is one notable event.
In Middle school, there was this 5/10 I was crushing on. I had decided to ask her out because I thought even my ugly self had a chance. Obviously, I didn't. But I had asked her out in front of most of my class (it was small because it was a private school) and humiliated dearly because I even dared to think I had a chance with anyone.
The only good thing to come out of this is that it cured my oneitis. Many cels don't grow out of it until much later.
