I'm so embarrassed! Help!

I really don't know what to do! So at school, our phones have to stay in our locker. I always follow the rules and I have very high expectations for myself. I'm late a lot because I stay up late and sleep in on accident, so I turn up my notifications all the way so I'll wake up. Well, I forgot to put my phone in my locker today, and it rang in front of the whole class! And my ringtone is Kim Possible's ringtone so... yeah. Embarrassing. I sit next to popular kids (thanks a lot teacher) and they were of course making a big deal out of it and saying horrible things to me. In my next class, I even had to leave because I was crying too much! I know I'm overreacting, but I still don't know what to do. Sorry I wrote so much. Thank you for reading this!
