Should I take this offer or not? A girl is turning 15 years and her mother for some reason chose me to be the one who dances with her at her party. 

My anxiety is terrible and I honestly prayed I would never had to do something like this. I have never danced and I know I would hate doing it

The girl just texted me to answer her back if I'm interested. I wish I could say no and let that be the end of it. 

My parents won't stop telling me that I have to do this, and that it will take away my anxiety, thus resulting in me becoming a better version of myself.  The practices are every Saturday and I just want no social interactions with people my age that I don't know.
