A lot of us go through this. I'm finally happy with wherever I've applied to & waiting to hear back from them. In my case i had filled out complete applications & even application packets were ready but since I got an admit from NEU , i didnt press submit / dispatched documents since I knew if I had option of choosing between NEU vs Uni X (where i was originally planning to apply) i would defo choose NEU.
But the wait to hear back is agonizing so maybe people are kinda over analyzing as they are anxious/nervous. Happens to me, in the sense " If i got in X or Y or Z from my list which will I choose?"
