I Hate Anxiety...

I have Social Anxiety and I have to go to a sweet 16 birthday party for one of my friends. We’ve gone to same church and basically grew up together so this party should be no big deal yet I’m on the verge of an anxiety attack because I don’t know who else will be there so I’m worried I’ll look like the stupid antisocial girl. And my parents won’t let me stay home because it may insult someone. 🤦🏼‍♀️ Usually id take my fidget toy to help but since I don’t know who will all be there I won’t feel comfortable enough to use it. I hate this and I’ve been doing better lately but it is now worse and I HATE THIS
