I have been doing some research online and I am wondering how strong the correlation is between genetics and mental health. Thought I'd do a little poll here to see if there is a correlation with our difficult child's mental health and family mental health and how closely it's related. This can be for adoptees as well if the birth family history is known. Is there a history of mental health issues? Are they the same mental health issues? How close is the family tie? That kind of thing. Just for curiosity sake.
