It may sound cliche or cheesy, but you all are beautiful in your own way! Because of your insecurities and society’s idea of “perfection” you can not see it, and it’s not okay! You don’t need to look perfect or flawless because you are human. You are who you are, and you’re special just by being you. And although you can’t see it, everyone around you can.
Don’t let anyone get in your head,
YOU ARE BEAUTIFUL.
Here’s a nice song to remind you so; https://m.youtube.com/watch?v=aoYEQgG4-JY
Have a good day and good luck in your exams,
