"Okay. I'd better explain the possible side effects to you. Uh, SSRIs are really safe - even if you overdose, although please don't because it'd be a waste of my limited supply - uh, it won't necessarily have any noticeable side effects but it can cause headaches, nausea, dry mouth -" 

She is basically recounting her list of Side Effects That Everything Has because she has no specific reference guide for Prozac. 

Wen Qing takes notes on the side effects. It would be a waste of their limited time for Marian to have to teach her these things twice.

Wen Qing is a really good student! Well, apprentice, whatever. Marian thinks she's great either way. 

Eventually someone shows up to, apparently, hand off Vanya to a different babysitter so that Larisa can go do a shop assignment or something.

Marian feels like she hasn't done NEARLY enough to help him. As soon as the door is shut behind that group, she turns to Wen Qing. "We should take some notes on him. Uh, I've started a notebook of files on the kids who see me, so that, uh, it'll be easier for someone else to take over later. What did you think?" 

"I don't know how good the medicines are but I think if Lan Xichen were watching him he'd need"-- she gestures-- "the sunlight, the exercise, the-- talking about problems when you're under a calming spell so you can think about them--"

"....Whoa! That sounds like a really cool way of doing therapy, actually! I - how much would Lan Xichen want people to pay or trade, to cast it for them? I was trying to think of what to recommend - I know in the mundane world there're some studies about treating PTSD by having people take MDMA, that's a drug that - well, people usually take it for fun, but it supposedly makes you feel really relaxed and safe and feel loving toward the universe or something? And then it's easier to think about your problems? The issue is that MDMA is, like, an illegal recreational drug that people take to get high, so it's hard for scientists to study it for medical uses." 

"What is 'therapy'?"

"It's - hmm - it's basically a particular way of talking about your problems and feelings that's supposed to help extra well? There are a bunch of different schools of it, that different people came up with. Oooh, if the void's in a good mood still, maybe I can get a reference book on cognitive behavioral therapy, that's really common so I'm sure someone's lost a textbook on it at some point..." 

"Is talking to people a kind of medicine?"

“So, uh, it’s normally a different speciality than mine. Prescribing meds for, uh, emotional problems is usually also a different speciality. But it looks like here it’s just me and I’d better learn how to do whatever’s needed. And I did learn a little bit about talk therapy in school, at least.”

"I don't think I would be able to get spells for it..."

A Mandarin-speaking teenager barges in. 

"I heard you guys have powder here," he says.

"He wants the heroin," she says to Marian.

Oh for fuck’s sake, seriously? 

“I don’t have heroin,” Marian says with as much dignity as she can manage. “Uh, tell him I don’t give recreational drugs. Does he…have a medical problem he needs painkillers for?”

She tries to get a better look at the kid. Does he seem like a plausible heroin addict? Any needle tracks on his arms?

"We give people medicine for illnesses. We don't give people recreational drugs. Do you have a medical problem you need painkillers for?"

"Yes. I'm trapped in this stupid school."

He doesn't have needle tracks on his arms.

Wen Qing considers this and then says, "Depression."

"...Uh. Right. Can you tell him that heroin isn't a treatment for that? And - can you ask him what symptoms are bothering him the most? Is he - sad, tired, unable to concentrate in classes -?" 

"Heroin is not a treatment for not liking school. What symptoms bother you the most?"

"I'm bored. I want something fun. Like drugs."

"His primary symptom is the boredom?"

....Well. Fair enough, kid– sort of? Having magic death monsters after you isn't something Marian would mainly describe as 'boring', but the food and the atmosphere certainly are. 

"Right. Can you ask him if, um -" damn it what are the questions on the stupid depression inventory, maybe she should just get it from the void... "Tell him to wait one second?" 

Marian says some flattering things to the void and asks it for a printout of the Beck depression inventory.

The void is going to be so helpful! Here! 

"Uh, I'm going to read you some of the questions on this and I want you to translate it and ask him?" Marian says to Wen Qing. "It's a clinical assessment questionnaire for figuring out how depressed people are." 

This is taking him WAY LONGER to get drugs than he was hoping. Why does he have to fill out a stupid form. The whole point of medical professionals is to dispense heroin.

He does not feel sad. He is not discouraged about the future, except insofar as the future sounds like it might contain fewer drugs than he prefers. He doesn't feel like a failure. He does get as much satisfaction out of things as he used to. He has never felt guilty about anything in his entire life. He... probably expects to be punished, because of all the crimes? People shouldn't punish him though, he'll break their fingers. He's not disappointed in himself. He's confused by the 'worse than other people' question, he's pretty sure other people think he's worse than other people but he doesn't criticize himself about it? Why would he criticize himself about it? Other people are boring and lame. He doesn't want to kill himself. Why would he cry, crying is for wimps.
