Anti-social person meets performing in front of people who make fun of you

Mmm anxiety am I right? I’m in dance classes since at my school if I were to do P.E. I would have to do a whole bunch of weird stuff. We have units which we learn new dances like cha-cha, waltz, and hip-hop. At the end of each unit we have to be tested on it.. What better way than doing it in front of people! Especially people who make fun of me! I sadly have to leave the room right after I dance in front of everyone because of an anxiety attack… How fun am I right?!
