I have family history and childhood abuse. I don't remember anything bad until I started kindergarten. However my mother was drinking and my father was physically abusive before that, if my mother was to be believed. Father's side of the family had depression and bipolar, and he may have been bipolar as well.

I was diagnosed with depression and borderline PD before being BP diagnosis. I didn't get a BP diagnosis until my late forties, about twenty years after the depression diagnosis. I knew there was something different with me when I started school, though.
