My sister (who I just in recent times have been trying to form a better relationship with) was diagnosed with Bipolar Disorder. I have spent years dealing with anger, anxiety and depression which I have blamed on sexual abuse in my childhood. I am wondering now if she too wasn't a victim of this relative. I can't just come out and ask her because it isn't something I can talk to people about and especially with family since this person was a very close relative. So, do you think she too could be a victim or are is it just that we both inherited mental illness.
