" Is depression considered a "comorbitidy" of abuse? Is anxiety considered a "comorbitity" of abuse? Is lashing out considered a "comorbidity" of abuse? "
That's quiet an interesting question you ask. Because not everybody who is abused gets depression or anxiety. When they do, it's considered adjustment disorder, or reactive depression. Also, after a trauma, not everybody will develop post traumatic stress disorder. What makes some people get it, and anothers not? Some depression/anxiety are thought not to be linked to any stress at all. I personally think depression and anxiety disorders have different etiologies.
Though it's a good question to ask, is any of the depression/anxiety a result of abuse? This study could be done by comparing autistics who have depression/axniety to neurotypicals who have depression/anxiety. Perhaps compare autistics to neurotypicals who have been abused the same amount, perhaps they may have something that makes them the target of prejudice, and see if the number of depression/anxiety sufferers are about the same. Though it would be hard to systematically define and control 'amount of abuse'.
