The key part of your self pity meltdown is “tinier chance at acceptance”. As previously noted acceptance is 4 or 5 out of every 100 applicants (50 out of every 1000… you get the picture) and most likely less because of all the recruited athletes. Your awards might have moved the needle a smidge but why obsess about it? You have a choice between 2 amazing schools and you’re whining about Stanford. Not an attractive look. As Cher so appropriately states in Moonstruck- “snap out of it!” Make your choice, buy a sweatshirt, wear it proudly and enjoy the next 4 years. It only gets tougher so celebrate what you have now.
