"Oh, yes! If the body's energy systems are dysregulated that can cause any number of symptoms."

He can feel his sister's Waves of Disapproval from here ("I feel a disturbance in the Force... like my brother talking to someone who uses 'energy' for something other than ATP...") but also bailing on a conversation after two sentences is... probably rude? Not in future him's best interest? "I-is it possible for them to be disregulated since... birth, or thereabouts?"

"Of course! In fact, you may be suffering from problems with your past lives. I am actually receiving training in past-life regression--"

The second therapist is little better.

"I practice acceptance and commitment therapy."

... He could justify to his sister the energy, but not the past life regression.

"...c-could you summarise what that is?"

"Well, to put it in as simple a way as possible, acceptance and commitment therapy is about accepting that you're miserable, and then realizing that you can do things based on your deeply held values anyway!"

"--is there anything about, um, for example, working out what miserable things are changeable and which aren't?"

"Well, that's not really the idea," the man says. "The important thing is that you can get the things you care about in your life even if you're miserable all the time."

... So, on the one hand, this does match with what he wants. He wants other people, as many of them as possible, to be happy, even if it doesn't make him feel better in any way.

But also... Things have improved for him? Even doing basic things? So it seems a bit... Premature, to assume things will suck as much as they do now?

"That's useful to know, thank you."

Third therapist: 

"I specialize in sex therapy from a kink-positive, poly-positive lens!"

... A promising start.

"I'm sorry, you probably get this a lot, but is this therapy about sex, or... Involving it."

"About sex! Therapy that involves having sex would be extremely illegal."

"I assumed so, but I wanted to check." ... He's going to have to explain his problems to a therapist to see if they can help. He is going to have to use his mouth words for this. Why. "I definitely have some problems... About sex, but not exclusively?"

"Most sexual problems affect other parts of your life too."

"--and you have experience dealing with those, too?"

"Certainly! I can address all sorts of relationship problems."

"... But not non-relationship problems?"

"I can help you learn to destress and do time management so you have time and space for sexuality!"

"Thank you." ... So far they're the best on the list, but... "I'll keep you in mind?"

"Thanks!"

Wen Ning gets a sudden urge to go take a walk. 

...as sudden inexplicable urges go, there are worse ones? On a walk he goes.

He stumbles across a Unitarian Universalist church with a cheery sign out front that says "Depression? Anxiety? Moral dilemmas? Difficulties piling up so high that you can't see through them? Contact a UU spiritual director today!"

... There's a fifty percent chance this will be whatever the Unitarian Universalist equivalent of "past life regression to align your inner energies with the cosmos". But also, even if that happens, he can say he talked to every available therapist and also the UUs.

(And the urge to take a walk could have been nothing... But it might not have been.)

He may as well try contacting them?

Here is a phone number he can call, and if he calls it he can book another phone call with Reverend Parker.

...it may take him an embarassingly long time to go from 'puttinh that number in his phone' to 'actually pressing the call button,' but he does so.

It turns out that Reverend Parker has a slot free this afternoon!
