Try to think a day ten years ago. Think about what everyone was wearing.
You probably can't. Think about what everyone's hair looked like. You probably can't. Think about who was dating who. Again, you can't think.
You can't think of any of these because they simply don't matter. No one will remember if you wore the same jacket for two days in a row. Just embrace yourself and live life. It'll be okay, and no one will care, so stop stressing yourself out. YOU GOT THIS!!
