On one side of the family, I have a cousin with Asperger's and aunts and uncles with depression, anxiety, and OCD. My dad seems to have moderate OCD and is a borderline hoarder, but no dx on those behaviors. Everyone in my immediate family has been treated for depression, but on a limited basis for everyone other than me. The other side of the family seems pretty much sane.

So although I'm not alone in the family, no one else's MI seems quite as serious as mine. At least I can stop the genetic trainwreck and avoid passing on these genes.
