Last day of secondary school!!

I've just had my leaver's day from secondary school and it was so bittersweet!! I'm so sad, but happy!!!! Is anyone else leaving this year? It's just so sad, there's so many people I'll never see again, and I've never realised how much of an impact they've had on my life, including the teachers! I mean, I'm going to the sixth form connected to my school next year, but two of my favourite teachers won't be there next year :( It's just so sad!!!!! I don't want to leave!!!!!!!
I got these questions always running through my head, So many things that I would like to understand
