Yeah, you're right. I could just imagine the outrage EA would get if they added a feature like that. I use Sims as my escape from reality as well and it's really nice to feel like I'm in my own little world. But honestly, I do sometimes get a kick out of seeing them freak out. It can be funny and it wouldn't be completely realistic since, as we all know, mental illness in the real world is not funny.
But yes, I understand what you're both saying. By the way, I have PTSD, OCD and I struggled with depression (and suicidal feelings) for three years, so I can relate.
