I was diagnosed in 2011 but refused to believe it. After having 3 psychiatrists tell me that I have BP and doing a lot of reading, I am sure that I do have BP.

Let me see...

Grandpa ran away from home when he was 37 to "find himself" leaving Grandma with 2 kids... not quite the "done" thing in 1917.
Aunt D was religious to the max and used to send letters carbon copied 6 times with nothing but bible verses and hymns in them to everyone in the family.
Dad I believe had unipolar hypomania - a very good thing indeed.
I have BP.
My brother is 15 years older than me so I don't know him that well.
I can see some BP traits in my kids but I'm not really objective about them.
My grandkids are all too young to tell.
