online "cool" kid on class groupchat vs offline loser in class HELP

soo i recently made a groupchat for my class, and i've made a terrible mistake!!!! i allowed myself to be me on it, talkative (chat/text), silly, stupid, active, unserious, bossing ppl around as the groupchat mod, what ppl would call fun ig?? and some of my classmates have taken a liking at me, teasing me, including me in stuff online, respecting me as teh groupchat mob boss and whatnot,...and it makes me feel liek i belong...but....like...none of them knows that im literally THE lonely loser of the class bro TT. while those ppl r mostly like social confident decent pretty handsome etc.

and because of something that happened i think they might have figured out who i am and will soon recognize me in class!!!!! and when i tell u i am literally the ULTIMATE loser like i cant freaking talk to people irl like i do ONLINE, im the only one with no friends in the class, i get nervous, i get awkward asff, i cant even show off my personal sense of style cuz i only have basic ahh old clothes cuz i cant buy any more, nobody can hear me when i talk most of the time, and im lowkey ugly bro

SO A MYSTERIOUS CUTE FUNNY GIRL FOR THE ONLINE ME IS WHAT THEY'D EXPECT BUT THEN THEY'LL SEE I'M ACTUALLY THIS LAME LONELY LOSER AND CRUCIFY ME HELPPP IDK WTF IM GONNA SAY IF THEY COME UP TO ME!!!!!!! i dont wanna disappoint anybody cuz who i am online is rlly who i truly am irl too (w my few close friends who i magically obtained for example, and like soem of my family) but i probaby won;t be able to show that at all irl!!!!!!! not initially anyways!! WHAT DO I DO

THSI IS WHY I USUALLY PRETEND TO BE KINDA DISTANT AND COLD AND BORING ONLINE WHEN PEOPEL I MIGHT MEET IRL ARE INVOLVED BECAUSE I DONT WANNA DISAPPOINT ANYBODY WHEN I START OUT AS AWKWARD AND NERVOUS AND WEIRD!!! but i slipped uppppp

ah btw ofc i didnt catfish or anything, unless being urself online but socially anxious&awk irl counts as catfishing. i said cute cuz i think people usually expect someone to be conventionally attractive if their personality is attractive online, like that;s what they hope
