Thanks for pointing that article out, Dee!
Genetics is a pretty weak factor in my family, I have/had 2 uncles on dad's side, but nothing else back to great grandparents.
With my step-family, though, it's in every single person going on the 4th generation that I know of. I do think a lot of it is having a parent use pills to "deal with life" that did more damage than the genetics would have, alone.
Hugs and prayers,
Amy
