I do not like it when RPers and fanfic writers give Italy a disorder or mental health issue, whether it be depression or autism. Italy was emotionally traumatized when Rome died (he was young too), but that doesn't mean people should diagnose him with PTSD or give him an inferiority complex. Anyone who plans on making Italy autistic has to be aware that there is more than one type of autism and that it affects each person who has it differently. It mainly affects communication and social skills, so if Italy had autism, he would have difficulty expressing his feelings and look away from the person when talking. Anyone who makes Italy a suicidal cutter has to be aware they could offend someone who went through that problem.
It looks shiny on the outside, but in reality, you are going to piss someone off.
If you think Italy should have mental health issues, that's fine. But please don't use it to attract Germanies, Prussias, Spains, Austrias, Romanos, bad OCs, rabid weeby fangirls, etc. That means you, you ome Italy RPer I keep on running into on Omegle.
