We all know this but so, so, so, so many random political and social factors go into any sort of award decision-making-- even moreso something like Fulbright. I am crushed that someone with your qualifications and passion didn't make it, kbui, but (as hard and impossible-feeling as it may be) do not take this as a "my hard work doesn't pay off, so there's something wrong with me."
You have a chest full of medals that many people on here (myself amongst them) couldn't dream to achieve, and you are clearly going to be a shining star wherever you go because of your disposition, work ethic, passion, and obvious acumen.
Cry it out, feel ALL the feels, but know you have a community of people here who think you are the bomb, and remember to choose to listen to them rather than the anxieteers in your head. Many hugs and tonnes of gratitude for the work you've put in on making this thread a welcoming place to ex-lurkers like me.
