My mom was extremely depressed through most of my childhood and would often scream and yell at me and my siblings ... she gave us the impression that it was our fault that she was so miserable, that we didn't help around the house enough, or that we were too disobedient etc .. She'd often complain about it all to relatives. I remember my grandparents and aunts sometimes visiting and telling me that I needed to treat my mother better. I was younger than ten.
She eventually started taking antidepressants and things improved dramatically; it's interesting to see how well adjusted my younger brother and sister are who grew up mostly after she started taking them.
