I found out both of my parents are diagnosed with schizophrenia and did not tell me until now

Repost from r/schizophrenia, I was recommended to try this sub.

I am 25F. My dad sent me mail confirming my lifelong suspicions. He told me my uncle has schizophrenia as well.

Background: Both parents have other symptoms and diagnoses too. They were only dating until halfway through my mom's pregnancy with me.

I was wondering if anyone is in the same boat... I am diagnosed with PTSD, MDD, BPD, and ADHD (phew). I just mention this because I have struggled a lot in result in my upbringing.

I have a great job, but am experiencing health issues, and this news has thrown me more.

I have bad relationships for different reasons with both my mom and dad. They have both been abusive and non compliant with treatment. The word schizophrenia was only used as an insult my whole life. I know i have never experienced hallucinations and don't share the same DX.

Does anybody have the same experience with 3 close family members being diagnosed? I don't know how to proceed. Research suggests strong links to being hereditary. They're both broke and in their 60s.

Is there anything I can do to support my parents during delusions, while protecting myself? Does the severity of this illness negate deluded abusive behavior in some circumstances?

Thanks if anybody reads. Sorry for all the questions. I hope this doesn't come off as fear of potentially receiving a dx... I just don't know how to help both my parents as they get older. And I don't know where my places are to help as their adult child.
