why does thinking about school give me anxiety?

This was originally Written on spacehey.

so like, in 9th grade i got bullied very badly due to some OTHER kids telling me a teacher was a pedophile when he really wasnt. okay wait story time..

some kids told me a teacher was a pedo, i believed it. a month later another teacher was talking about him and i told him about the "pedo" teacher.. and yeah, i wont go on because that part gives me flashbacks and yeah, just guess what happened i guess.

now, maybe a year or year and a half later, i still keep getting flashbacks and anxiety attacks about that happening again. Im online schooled but these flashbacks are kind of affecting me in the online school because im reminded of when i was in public school and that happened.

is this PTSD? wtf is this? Is it anxiety? I cant tell anyone outside the internet because they'd compare their problems to mine, nor do i have a therapist.
