I desensitized myself years ago by looking at the worst I could find. It was bad for my mental health so I stopped. Now I'm no longer desensitized and a lot of things affect me again.
This is my go to type of therapy. It's about re-centering your focus so that your mind stops looping back to the trauma./ Where it becomes problematic is then weaning yourself off the game to healthier pursuits.
definitely shouldn’t be an only solution, socializing and talking it over are also very helpful. i think the game just has a very specific level of escapism that neutralizes thought loops which improves the efficacy of other coping mechanisms.
Serious answer: I remind myself it's normal to be shocked by some stuff people do/create. I check the content against my ethics, and try to decide if I'm being uptight or if it really is messed up. If it's something that isn't unethical/harmful but I just don't like, then I remind myself that not everyone needs to share my tastes.
If it's genuinely terrible I allow myself to feel the anger/sorrow for a bit, try not to let it become excessive, and congratulate myself on having limits that fit my ethics. I remind myself that good people exist and they are the ones I want to support, emulate, and engage with. As others have mentioned, distraction can also help. Video games, music, socializing - whatever will move your train of thought along.
I once worked in a questionable industry, where there was no such thing as NSFW (nor NSFL). My coworkers and I would have competitions to see who could freak each other out the most; this was back in the goatsie, 2g1c, and bme pain olympics days. 🤮
It’s not my thing, but at the same time it doesn’t affect me much anymore. Though, as all things evolve over time, things probably have only gotten worse.
