An odd thing in me? pls i need thoughts

I just think this is a bit concerning cuz i literally almost died. Okay so, in my school year (10th grade that i passed) i was in a school that wasnt rlly great, its private school cuz most of the public ones are rlly bad

in the first semester, in school(A) i had couple of probs w my friends abt a random shi, anyway, i met a guy who was friends w the ex of my friend(before they broke up) and idk it lwky felt like he had smth for me but i ignored it and did my best to treat him as a friend altho i lwky didn't like talking to him.

In the second semester i moved to another school(B), worst time, i got severe depression and literally couldnt attend the school or pass the exams. and i was in a tornado of attemps and SH

and then i returned to school(A), things were normal ig but like one day i went to the upper floor to go to the WC, and suddenly i was literally slammed to the wall with hands wrapped around my neck.

The guy that i mentioned was literally choking me, had this almost crazy look on his face as ge kept saying "why did you come back"

idk why, i literally couldn't scream, my brain just went blank.

Idk why tf he did that, like, a sick joke? was he serious?

but anywho, if it werent for two girls from his class that pulled him away, god knows what could've happened, they just left with no other word or checking if i was okay.

and god, i literally had a hard time breathing for the following 4 minutes as i hid in the bathroom, i cant remember if i cried or not tbh.

And i literally didn't tell anyone, i didnt report him or tell anyone abt it, i almost forgot abt it,

so its currently summer, close to the beginning of the school year(11th year)

i told my mom abt it an hour ago, and she was flabbergasted and so confused on how the hell i just...did nothing abt what happened

Clearly traumatised her

i just wanted to spill it, i think its bc of the sudden shock that my brain stopped working? pls if u have any thoughts tell me :/
