There are only three possible outcomes now, leading ultimately to just two: either you're in or you're not.
And whatever the outcomes are, you will still be you. You will still have the same passions and goals. You will still do what you like, avoid what you don't, and be the same person you've always been.
Don't let this one outcome control your sanity. This is but one major event in a relatively young life, still mostly unwritten. Take a moment to push back the computer, turn off the screen, and spend some time with family and loved ones. Go for a long walk. Cook an elaborate meal to share. It's your holiday season! Enjoy it! And stop worrying. Heck, if I were you, I'd leave the house for all of Jan 2 and not return until well after 5PM. Because... if you get even a missed call with the right area code, you'll already know what it's for. Why worry yourself sick?
