Hello, i might be a little late. I was in the same situation, we had a social event where we become delegates for countriee and attend conferences, debate etc. I also have a massive socail anxiety so i was really scared. But with my parents force, i ended up attending the event. Its not like i talked much or interacted with others but i can say that taking part in these type of things might axtually help you out! I learned how ro examine people around me, gathering more thoughts of how to talk with less panic. This helped me, but it might not go same for you. But why dont you give it a try? If you dont feel good then you wouldnt attend again! Take care, and think of the best. We love you! :D
