I'm fairly positive I will be getting rejected from WashU, as those acceptance notices were sent by the department, which stings a lot because it will be my first. However, I haven't received a formal rejection yet, and it sounds like you haven't either, so don't get too down! You never know what might happen! (I say this, although I'm struggling to not be anxious, sad, or scared myself!) I think I've checked my application and login portals probably 1,000 times every day for the past week and a half!
