Do other fellas also feel the same😭

I've been so isolated from people my age irl in the past one year due to all the college prep n shi. I'm feeling weird about joining a college. a uni. where I know my school alumnis and my school mates are going to be there. and as seniors to me.😭 my confidence has gone down the tunnel already and having to call people my age and specially ones I knew from school as my batchmates, to seeing them being my senior😭 It's just feels too embarassing. I'm not the kind to disrespect my juniors though or my age people but you know what I mean.

On top of that, there's is this irrational fear that if my school mates are going to find out I'm their junior, they are going to judge me.😭 or I am going to feel like I'm still in school. I hated my school life. I was just glad I graduated or passed school whatevess. I had a studious image in school. which I could never change in my entire school life😭 Actually I was not that nerd but because of me being on top in every class and also being a bit introverted, I never beat the allegations of a nerd lol. I just want to live a new life urgsgshh.

how do I stop feeling like people from my past are going to still view me as that studious introverted girl? I know you would be like fck it. noone gives a shi bruuuhh but still.😭 I feel like everyone else just knows each other and I am the only one who is going to be left out not knowing anyone and meeting new people😔 It's the worst to join a friendgrp where everyone knows each other from school days when they met through debates competitions MUNs nd all😭 what do I even doo😔 I can't even go back few yrs and make some changes.
