Should I go to the reunion or not?

Hey guys so I am a 21M. My school classmates from 10th are having a reunion tomorrow and everyone is invited over the WhatsApp group now during school time I was a shy boy not like I was not talking to everyone or like that but I used to have a close circle of like 3 friends and others were just like we see him everyday from school so we talk kinda and know from my circle of 3 no one is going I am still like the person who talks less but I can vibe with anyone. I don't know if I should just go or not (ps: also I am afraid of how will they react me being there )
