please help me!!!! plz!!

Okay so I have a cheer dinner tonight and I don't feel like going. My mom was trying to force me to go and socialize bc I was acting anti social. I really just didn't feel like going to the point where I started crying. Now I really don't want to go bc I feel like everyone knows that I was crying because I didn't want to go in. I'm usually not like this but here lately I've been different and my usual outgoing self. Someone plzz help me!!
