Listen. I cannot stop you from being insecure, and I'm sorry. But think about it.

You died. You're friends and family are hosting a funeral. Your best friend goes onto the platform and begins a speech.
What will they be saying?
"*name* had the perfect body, a shiny smile, and amazing hair."
Or,
"*name* was kind, intelligent, and funny. *name* was such a pleasure to be around."

The second one, right? So why does it matter how you look? Your personality is worth more then words. So own it!!
