Any advice?? Rant

Hi so I’m currently at my school and I have nothing to do. I have an Exam in about 2 hours and I’m supposed to be studying with my best friend but she ditched me so now I’m super pissed and super stressed studying in front of my locker all by myself. She walked past me like 2 and when I tried to call her she totally ignored me because she was with the Popular people and she is constantly wanting attention. I’m on my period Rn so that’s why I’m so emotional and pissed and mad and sad. My crush who most likely has no idea who I am openers the door for me and smiled and I was so pissed I didn’t even say thank you I just walked right passed him and his locker is close to mine so he’s probably gonna see my crying and pissed. So yeah my life is shit, my friends are toxic, and I’m about to fail an Exam and get yelled at by my parents
