abuse will be stopped before it occurs

in Stockholm, Sweden when I was about 10 years old in school I had a male teacher with a very finnish sounding name. I was flirting with a girl in my classroom and she started to giggle. the finnish teacher got furious and violently threw me into the tables and chairs in front of all my classmates. then he grabbed my neck and made me walk on my toes into another classroom. then he went and brought the girl I flirted with and started screaming in my face until I started to cry while he made the girl watch. me and the girl stopped talking with each other. she changed school after a while. my classmates never did anything to help me, but they did like to harass me. I had trouble flirting with girls with the intention of dating for the rest of my life.
