On my father's side, his brother suffers from something mental, but hasn't ever been open about it. My father's father killed himself, and that's as much as we know.

On my mother's side, my grandfather was taking lithium for bipolar and became stable. My aunt suffered from panic attacks and anxiety, my cousin suffers from anxiety and depression, my other cousin has ADHD and possibly bipolar, my other aunt has ADHD, my sister probably has bipolar but hasn't sought help, and I have bipolar. My mom probably has social anxiety, but hasn't wanted medication.

It seems my oldest son is suffering from depression and anxiety and I suspect ADHD and/or bipolar. (We're working on that now)

It runs rampant in my family.
