As someone who grew up with severe OCD (and, I now believe, undiagnosed HFA) and whose behaviour in times of extreme fear, lashing out at my parents verbally and physically, would be described as abusive, I have often asked myself what, if any, is the difference between me and an adult perpetrator of domestic abuse. How much should mental illness be taken into account? Do I deserve to go to prison? etc. etc. I do not know the answer, but there is definitely not enough support for families suffering in this way.
