Mercy

She's a doctor, so she most likely already knows how the distortion goes

That being said, she makes sure to talk to you about it and keeps your specific quirks in mind, as she knows every person's experience can differ

She would have you sit down and talk about casual things while being completely attentive and writing down helpful information that came up

She works on several methods with you in hopes of helping lessen such drastic thoughts

She helps you analyze any problems/predicaments you have, from the smallest inconvenience to a huge and important issue, through "thinking in shades of gray," meaning observing your problems on a scale of 0-100 instead of simply either-or

When your distortions cause anxiety that gets overwhelming, she helps you calm down by taking you to a quiet, private place and sitting with you

Maybe rubs your back or wraps you in a blanket or brings you warm tea with relaxing components to sip on

When you get too hard on yourself, she works to comfort you and tell you everything will be okay, that you're doing great and that you can take your time

She really does go above and beyond to help you and comfort you

Reaper

He doesn't have the distortion himself but he certainly does understand that method of thinking, just maybe not to such a drastic level

What he doesn't understand, he finds out through research and from you

Tries really hard to help you work out your problems and such, even though it might take him a few tries to figure out what helps and what doesn't

Helps you figure out your problems and tries to work them in the way of shades of gray rather than the all or nothing method

He understands that things can become too overwhelming or uncomfortable sometimes, so he works to make sure whatever environment you're in, whether at home or when he takes you on a date or even when just out and about, that you're comfortable and have a way of coping and working things out

If you're comfortable with it, he'll wrap you in a cloak of smoke when things become too much to help calm you down

It's like a giant Reaper hug tbh

All cozy and safe and stuff

It might become a security blanket in a way

No rough decisions or rampant thoughts in the giant Reaper hug

McCree

Well you tell him about it, he immediately learns all he can about it

From you, from books and the internet, from people of the medical field that he knows

He wants to make sure he can help if needed and to make sure he doesn't slip up or make you uncomfortable

He knows so much stuff after cramming

When things get to be too much in social settings, he wraps you in his serape and/or gives you his cowboy hat to wear as a way of shielding yourself

Will take you to a calmer, quieter setting as quick as he can

At home, he'll help you piece out advantages and disadvantages to your thoughts, feelings, etc. as way to help you ascertain yourself with such things

Tries to help you figure out how to go about problems a better and more developed way rather than either/or, and works to stop talking in an either/or fashion himself in hopes that maybe helping a bit

If there's things he can't help you with, he may suggest something such as therapy to help you work things out where he can't really do anything

He's trying his goshdarned best
