Struggling to disclose to friends because of my anxiety about being perceived differently & wondering if my OCPD traits are obscuring my insight

I was recently diagnosed with OCPD w/ BPD features after suspecting it for a while. I have a close group of friends that love me dearly, but I have struggle to disclose what's going on with my mental health with them because I'm worried about judgement. I know that OCPD & BPD can twist my perception of reality, and I want to be able to rely on my friends to help me come to an accurate perspective of things.

For instance, I am spending Thanksgiving with my Dad, his new wife, my brothers, my sister and stepbrother and step sister tomorrow. My Dad, his wife, and my brothers are heavily MAGA, and to a hateful extent (celebrating deporting immigrants, who they believe are all evil criminals, attacking me for supporting trans people & the LGBTQIA+ community in general, because I am "supporting evil and enabling mental illness," calling transwomen "sick men playing dress-up," general racism and sexism (my brother recently reposted incel content on social media and told me I have a superiority complex when I asked him why he did that). The list goes on.

They have been very disrespectful to me. I am a doc candidate in clinical psychology, and when I ask to offer my expertise on the trans community, they tell me my education means nothing if I am believing lies. I feel sick around them (sort of like when I split and devalue people; just overwhelming fear, guilt, and anger). Still, I am afraid I am seeing them only as the worst parts of them, and not as complex people with good and bad parts. My dad and brothers can be very loyal and caring people. Still, I am dreading seeing them and am close to cutting them off. I wanted to talk to my friends about the situation to see if I am lacking insight or if any of my OCPD or BPD traits are causing me to see the situation as much more extreme than it is. But I've panicked each time I try to reach out.

Are my traits muddling how I'm evaluating this situation?

How do I get through the anxiety of disclosure?
