I  (32 non binary) was told that bipolar disorder can be caused by environmental and/or hereditary factors and unfortunately I believe I am a product of both. 

To keep everything short, my one parental figure caused me many hardships and great suffering in my life. They themselves had Bipolar type one and I have been diagnosed with PTSD and Bipolar type 2. Growing up with them I feel I lived in two different worlds each with their own set of rules. I never knew what I was walking into when I went home and though I tried to stay and be there for my family, it came down to my parent's well being or my mental well being. I haven't spoken to them in several years and I am proud to say I feel safe and stable for the first time in my life. 

While a part of me lives in fear of them finding me (so much so I am to scared to say genders thinking they may somehow find me with this post), another part of me feels guilt and longs to mend things between us. I have been having nightmares about them screaming in pain and needing me, but I can't help them and it is killing me every day. But, as selfish as it may be, I fear for my mental stability if I were to try and contact them.

I know I can't be the only one that has gone through something like this, so I was hoping to ask: 

Has any one been able to muster up the courage to confront their abusers/probable cause of their mental disorders? If so, was it something you regret doing? Is is even possible to forgive without confronting the person who caused you so much heart ache and fear? Even if they don't believe they did anything wrong?

Thank you for any advice/stories. If there are any grammar or spelling mistakes please forgive me and let me know so I may fix them.
