<human>: Could you distill the essence of the text into 1-3 sentences?

I am a junior in highschool and the winter formal/sadie hawkins dance is coming up. For this dance the girls typically ask the guys. Last Friday after school I was standing around by myself at the lunch tables, and one of the very popular pretty girls (her name will be Ally) came up to me and pretty much asked me to go to winter formal with her. I have zero female friends and one guy friend so I was really surprised. I asked Ally if this was a prank, she laughed and said no she thought I was cute. That made me think she was serious so I said okay and she asked for my phone number and said she'll text me later that day. 

Since around 8pm Friday night I've been getting tons of texts from several different numbers I don't know, around 20 numbers, saying stuff like "did you really think Ally would go with you?" and similar things making fun of me. On Sunday I only recieved like 10. I did not have school today (Monday) but I recieved a lot more texts. I guess Ally gave out my number or something like that, I'm not sure.  I have school tomorrow and I'm not sure how to handle it. I'm afraid there will be many people that know about this and will make fun of me. Should I say anything to Ally? I also think I could convince my mom I'm sick to stay home, but that probably won't fix anything. I'm not looking to get Ally or anyone in trouble, I just want to be left alone and I have no idea what to do. Any advice is appreciated thank you
