to be completely honest in this situation i wouldn't worry about it
getting "shamed" in school is the equivalent to getting told to kill yourself on the internet
if you dont let it affect you as much it doesnt hurt as badly
trust me i've been there but i sorta built confidence in myself to stop giving a forget over time
last year i was always concerned what people would think of me and i used to think i was fat and stuff and whatnot (even though im not) and i always thought "what are they going to think of me now"
the truth is if you stop giving a forget you stop giving yourself something to worry about
not saying social consequence can fade just by not caring but in the event that someone goes "oh look at that kid hes got nikes instead of "yeezys" " then instead of cowering due to their judgement you tell them to forget off or just not care about it
