I Really Fucked Up

Guys help, I think I REALLY REALLY fucked up this time.

So a while back, I did one of those random demographics survey that comes in to your UW email from time to time. The survey was legit, but I bullshitted it by saying my ethnicity was "Yakubian" as in https://en.wikipedia.org/wiki/Yakub_(Nation_of_Islam)

Why tf did they make the ethnicity field a user input instead of just multiple choice with an "other" option ffs WHY????

So right now, several months later, me, who is as white as blackboard chalk, just got an email saying I've been offered the "Undergraduate Achievements Award for Black Canadian Students".

Apparently, I have like top 10% grade average in my program, but one of the top grade averages amongst the candidate pool (sorry my bruthas) for this award. I'm so fucking scared, not just because I don't deserve this award obviously because I'm not black at all, but because I don't know how I can explain to the administration that because I shitposted on a demographics survey now almost $30,000 of award money just got passed up from deserving black students to go to a wyteboi.

I honestly don't know what to do. Do I turn down the award? How would I even do that? How can I even explain it to them that I'm not black? They probably thought "Yakubian" is some sort of African ethnicity, but how would I even correct them on that?

Please help me, the amount of money involved is too high for it to wantonly go to some melanin-less kid like me.
