Quinn, nonbinary, sold self to cure self, 3rd person

Quinn couldn't believe they really came here, but at the same time, this was the only way out. Their mental state had been declining for a while, and they didn't want to think about what could have happened if they didn't find a solution.

So, here Quinn sat with a peculiar creature, a fae. The research done just to have a solid idea of how to negotiate with one of these things would be well worth it soon enough.

"You desire to sell yourself to me?" The creature stood eerily still, its greenish skin barely wrinkled by the tug of a little smirk on its mouth.

"I have come to seek a deal to make, exchanging ownership of myself for something in return," Quinn replied, as courteous as possible while avoiding vague language that could be exploited, or direct eye contact.

"But of course, you must have heard of our delightful treats, yes?"

"I have, but that is not what I seek. I want to cure a certain ailment of mine."

The mystical stranger pauses, before probing further. "I see. What is this ailment you seek to cure?"

Quinn cleared their throat, carefully recalling their notes on how to describe it. "My mind has been filled with disorganized and persistent thoughts of things that disturb me, and feeling strange emotions I don't like or understand. If it should seem beneficial to myself and who it is I might make this deal with, I would give my soul up to one who would cure me permanently of those unwanted thoughts and feelings."

The fae creature seemed to smile as Quinn recited their speech. "That is your offer?"

"Yes."

"Very well then," The fae nodded, and seemed to pluck a small thing, like a seed, from thin air. "You're more clever than most human clientele, deliberate and mindful in deals, though none less careless with your desires."
It held out the seed in an open palm. "Eat this, and it will be as you say. The thoughts and feelings you speak of will be banished from your mind forever, and you will belong to me."

Quinn carefully picks up the seed from its hand, and gives one last polite nod before popping it in their mouth. As they swallow it, the last thing they see is the toothy grin of the fae in front of them.
