This presents a few possible complications.The largest of which is commonly referred to in the RPG community as bleed.
I'm going to detail the types of bleed really quickly, but to be certain. Bleed is expressed as your characters feelings affecting change on you as a person, or vice versa. Bleed isn't inherently bad, but it can be disruptive. Both to play and to formation of character. And it is generally bad to not recognize when bleed is occurring. But you generally can't stop yourself from feeling feelings... That's part of being human... I think.
There is Bleed In, this is bleed which occurs from your own desires, what have you are bleeding into your character.
Say you RP with your wife, or husband. You out of character have a predilection to being nicer to that person typically. But that isn't fair to other players. And it's an example of Bleed In... Your love for your spouse, bleeding in on your characters desires and motivations.
There is also bleed out. What started my journey on researching bleed was a moment about 2-3 weeks ago, where I was paranoidly raving at X-HELP that another player was cheating, and that I had logs that showed them getting back online within 10 minutes of an event occurring and then starting aggression on my character. And it was just... All too convenient, but it was a case of bleed out, my character's opinions about this character, bleeding out onto my desires, fears, and emotions about the player and the character. And I took a step back a few hours later and realized that I had done myself no help in this paranoid raving. Bleed out can often have the most negative of consequences for you within Sindome. As it can turn the spirit of cooperative competition into competitive dickery.
There's also something called Ego bleed, this refers to personality or even syntactical elements leaking in and out of character. When people talk about saying say before sentences out of character, or talk about having used Sindome slang IRL, this is one of the types of bleed, that is actually relatively harmless until it reaches a certain degree.
I'm going to detail a couple techniques here for dealing with Bleed. Not preventing it, because often it's not something that should be prevented, or even can be prevented.
But a tool for managing it when it occurs, so that it does not impact you in your real life. Or in your interactions with others on OOC channels. My goal is too by the time you're done with this guide and the associated reference materials, have given you a few ideas on tools for mitigating bleed, if you have it... Or to provide some effective management tools to suggest, if you don't.
The primary one I will recommend as it is the easiest, or at least least time consuming... This is called Immersion in other experiences. If you have played a stressful session, filled with plotting, crying, tears, work, stress, killing, torture, being tortured, what have you... Don't just leave it there, don't just go to bed, or go to your work in that amped stressed out state. Take a small amount of time, immerse yourself in something else for about 20 minutes. It could be doodling, it could be another video game. Just palette cleanse. Take some time, and focus yourself on something tangentially related at the closest... And then get up and carry about your every day life.
The next tool I want to talk about.. Is a heavy one. Demasking/De-roleing, is something that take a little more effort, and is harder to do in Sindomes context. But it will eventually help in spades. It will involve spending an hour or so after stressful events in game, writing it out, writing out the feelings, speaking them out works too, the important part is just getting them out there. Expressing them to the lampshades and potential people around you works, but is very close to rules violations. So I don't recommend it. But as you do it... You should take something that you associate with your character, and kind of... Discard it in some fashion. I actually went out and acquired a specific type of tea to drink that I'm working on associating with my character in my mind. And when I log off for the night I have been writing out some things... Like what I did well, what I did poorly, what I need to do more of, tasks for tomorrow, and so on, just something to get my feelings out about the day. And sipping that tea, so that when the glass of tea is done, I'm done for the day with my character.
Some other methods I know of or used in the past, like signalling, or debriefing, aren't allowed by Sindome's rules. So I won't detail them here.
I'm going to list my sources down here, so that you all can read through them. But they are relatively short, as this is somewhat of a niche topic. Even within the RP spheres.

(Specifically the essays about the magic circle, and pulling the trigger.)
I think these are all important things to consider and that researching and discussing bleed is a good idea. Though as a warning, do try and keep anonymous or keep OOC any information you post here if you post any at all. And keep the subject material on Bleed itself. Not on any specific events, characters, moments of bleed, etc.
Part of learning to be a better RPer is learning to mitigate and/or manage bleed in an effective fashion so that it's channeled properly.
