emotional

yesterday I had like a major breakdown and I could not stop crying and it was really embarrassing because it was before I had to cheer at a varsity football game and so what happened was my older sister brought my hoodie but she left it in her car so I had to walk to get her keys then my other sister told me her car was parked in another place then where it actually was and I was getting super stressed and then I had to get back inside of our school and all the doors were locked and I had to walk around to the side of the school and those doors were locked to and I just broke down crying then I was thinking about what had happened earlier that day with a boy and I started crying even more but I didn't even like this boy that much but I couldn't stop myself and I don't like to talk to people when I get sad so I thought I would ask you guys for some help one here thanks :)
