Interesting point, Vickie. To make my post more organized:

Paternal grandfather - suicide, had two sons, passed something to my uncle, my father was spared. My uncle had 4 sons, none are affected as far as we know. My father had two daughters. I am diagnosed, my sister may also suffer.

My maternal grandfather had bipolar, had three daughters, all three have some form of anxiety and or depression. My mother had two daughters, I am diagnosed, my sister may also suffer. My other aunts each had two children, one child from each aunt was affected.

Wait, that's still confusing...

(While we're at it, can someone explain what a third cousin, twice removed is? LOL)
