You're fucked. You thought you were going to be someone, but now it's obvious you're nobody. You haven't got as much talent as you thought you had, and there was no Plan B, and you got no skills and no education, and now you're looking at forty or fifty years of nothing. Less than nothing, probably. That's pretty heavy. That's worse than having the brain thing, because what you got now will take a lot longer to kill you. You've got the choice of a slow, painful death, or a quick, merciful one.
