You need to get a little perspective on this for your sanity’s sake. Do you really expect a letter from Stanford? Because unless you are a highly recruited athlete, I do not understand why you would, especially as you seem cognizant of the low acceptance rate. There is nothing you can do but wait, as everyone else is doing. I know how tense all you seniors must be at this time, but thinking about it to this degree is not going to change anything, so you might as well distract yourself with living life as normal. And please do not obsess about Stanford. You’ve done what you can, and life will be what you make of it, no matter where you go to college. Best of luck.
