Well, if it's not a mistake they've made somewhere and I do get the money, I'd actually spend it on good, healthy food, and the right amount of it.
Outside the realm of food, I'd try to fix up my room so its a cozy place to be outside my little computer corner so I can remove myself from it more. And I'd get new clothes. Something more proper and mature than what I have now.
Oh and I'd get that GOD DAMN GUTS FIGMA.
Also Drossel.
