i made someone feeling like they want to die

i'm 15 right now and i must admit that i was reaaaally a fucking asshole. i bullied this one kid with my group of friends and made the kid bled. it's not that bad though but stiiiill, that was really not cool. the kid's father came and scolded me and my friends. i don't know why the kid's father didn't report us to the principal but we were so fucking arrogant and we just scoffed at the kid's father with a smug face. after that, we bullied the kid even more harshly, not physically, but we slander the kid and make all the kids ignore her, something like that, there's more, but i can't remember since it happened when i was 8. the kid couldn't stand our harsh treatment and during our maths class, she suddenly went out of the classroom after i teased her and ripped her book. then suddenly, she climbed on the school (balcony?) and tried to jump to end her life right there. i was so fucking shocked and i was stunned for a moment. when i recovered myself, i realized that it all happened because of me. lucky that the kid was hesitant about jumping off. i shouted with all my energy and screamed TEACHERR!!! and i went out of the class and grabbed the kid to keep her from jumping off. i cried and said i'm sorry multiple times and i begged her to not end her life. the teacher saw us and immediately pulled us down. the incident was reported and she went to counseling and all. she didn't report about me to the teachers and i don't know why. i mean, i totally deserve it. and guess what? i never thought in all my life that she would be the greatest and the coolest friend i've ever had. she forgives me and bam! we suddenly became close. we started being friends when i was 9 years old or smething. we're still friends right now. and i have to tell you. DEFINITELY DO NOT MAKE YOURSELF BE THE ONE WHO MAKES OTHERS SAD AND DEPRESSED. TRUST ME, IT'S NOT GREAT.
