^Too true.
One thing that MIGHT help is if we can manage to figure out which illnesses are nature and which are nurture. We've made some strides in the nurture department, compared to 50-100-200 years ago anyways, talking about abuse is more open (though still shockingly hidden in way too many cases)... there are places to go, if you're being abused a cop won't say it's a family affair and walk away... it's gotten better, but there's a long way to go. We definitely need continuing education in that front.
But on the nurture part, we're starting to know our genes, can ID some... hopefully we'll know for sure one way or the other if any mental illnesses are genetic or not. If they are then folks can be advised that maybe adoption, surrogate, etc would be an alternative if they don't want their children to 'get it'... just like they do with diabetes and such you know? Still their choice of course, but if someone has struggled with this thing their whole lives, and thought it was just nurture then they might figure that just being a different parent from what they had would prevent their kiddos from having to face that particular problem... and they might feel bad for passing the genes on... I could see that being a possible reaction, especially if your illness has been a plague for you?? Flip side of course is if we find out for sure that it is NOT genetic, 100% nurture, then we can make sure that the folks who have an illness and want babies know that and then they can do what they can to make sure their kiddos are happy. Education either way is a good thing IMO... it gives you more choices and more control over your actions.
But then there's also always the possibility that no real mental illness existed. Revenge, for instance, isn't a mental illness... it's a goal, and can have horrible results, but even the most totally sane, never abused, perfectly normal person can get revenge into their heads if they're pushed far enough... of course having the cojones to carry it out... different kettle of fish. I've thought of some pretty mean paybacks in my time, but the worst I ever inflicted was withholding my cooking (specifically desserts) from my BIL after he did wrong and then yelled obscenities at me for it... so... yeah, don't think anyone'll be nicknaming me Terminator any time soon... *shrug* Is my aversion to violence any more of an illness than another person's liking it? Who knows. There's SO much about the brain we just don't understand... yet.
