I'm very sorry. It's a terrible, terrible, heartbreaking process.
It makes me feel better and worse to know that it is also largely random. As a rejection letter I got many years ago put it, there are many equally qualified candidates, and while the schools try to be as systematic as possible, the truth is that the reason one person gets in and another doesn't is often that there is no reason. The schools can talk about match, but match is often code-word for 'one professor liked the guy with the hat because he likes hats.'
This is not sour grapes, because that's not the position I'm in, but I am bitter.
