It is difficult for individuals who have never experienced mental illness to empathise with those who live with it on a daily basis. They are absolutely brilliant (in retrospect, I should not have started with a household of three Sims, each with social anxiety, bipolar I, or depression).
In January, I chanced upon Depressed Trait by saphryn and, of course, gave it to the Sim I named after myself. A few days ago, I found several more similar mods. I downloaded Social Anxiety Disorder – Trait by iridescentlaura and Bipolar Trait by emile20 and got to playing. Something that has been rising in popularity in the mod market allows you to give your Sim traits related to mental illness. For simmers everywhere, making the perfect Sim is always fun – you get to customise appearance, voice, personality, clothing, and aspirations, all of which will affect the way your Sims behave.
