Re: Inclusion Ideas for Sims 4
EA has always tried to avoid the "darker" realities of life when it comes to The Sims. Those topics can become very controversial if they are not presented very carefully and even then, you'll have many who will feel they are not included enough. Simmers have been asking for wheelchairs and prosthetic options for a good long while, since Sims 4 began many have wanted the elderly to have the option of a walking cane. Again, the problem lies in the fact that these very real situations can be triggers for people.
There was the "insanity" trait that had to be renamed the "erratic" trait because enough fuss was put up against it. I found that entire scenario ironic since so many people hated the way the trait made their Sim act, but they all calmed down when the trait's title was renamed and yet the Sim still acts that way whether it is called erratic or not.
If you want inclusion for an illness from physical, mental, emotional or spiritual, you'll have to look elsewhere. EA avoids even using the term depression, opting for moody or sad and in all the mood deaths a Sim can die from, sadness is not one of them.
The best you can do is search for mods and CC. There are people who have worked to make custom traits for many sorts of mental illnesses and a few physical problems. There are also those who will make props for medical equipment, but those are more objects than usable. The real problem often comes with the animation aspect, however.
