I think that as parents, we all have to do what we can to educate the masses. Most people, honestly, don't understand mental illness and how is affects the individual. And unless you have raised a difficult child, it is very easy to brush it off to bad parenting. What they do see is high profile crime cases where the person uses mental illness as an excuse for their actions.
I think for so long, the fact that someone had an illness was hidden from view. They didn't attend school. They didn't enter the workforce. My great grandfather was locked up and died in an institution because of epilepsy---at least that is what my grandmother was told was the reason.
I talk to everyone I know: lawyers, judges, educators, law enforcement officials, doctors. I am open and honest about the issues difficult child has faced because of his mental illness, but I also make sure everyone understands that I don't excuse the stealing and lying and drug use.
I think a national effort must be made. Some of the issues came to light last year when that state made the mistake about the law about giving up a child because you couldn't parent them---and they had parents crossing state lines for help----so they altered the law....
I am fortunate to be educated, to live in a small community where I am well known, to have some financial resources at my disposal and a strong support system...I don't know how in the world others survive the trials of raising a difficult child without those supports around them.
