You have POTS. Which is fainting disorder. It wasn't easy being an outlaw with POTS because sometimes you've fainted mid job.

You and Arthur were in camp, about to head out to scope out a place. When you had stood up to start walking with him, your vision got blurry.

You slowly stopped walking and stood still for a moment, unsure if you were going to faint.

"Are you alright? Are you going to pass out?” Arthur questioned, knowing everything about your disorder.
