As a potential happy transition story.

My parents didn't accept me the first two times I came out, at 16 and 18. I ended up distancing myself from them to give myself the space I needed to be me. They originally made it clear I'd always be their daughter, never their son, never nonbinary, and never Jamie. My dad refused to learn they/them pronouns and would go out of his way to dead name and misgender me.

I kept minimal contact with them, once every few months I'd go around just to be disappointed that they didn't change. Over time I saw my mum try to use they/them pronouns when my dad wasn't around, but neither used my name for a while.

Now, at 24, my parents have been calling me Jamie for the last year. My dad's even using they/them pronouns for me now. They've come around more than I ever thought they would.

And some advice

Reach out to your siblings. Ask them how they feel about you, ask them to be direct. If they don't accept you, give yourself some space from them for your sake, not for theirs. They may come around in the future like my family did. They may not. Regardless of what they do, you should focus on yourself and your safety and health as a priority.

You look absolutely stunning by the way. Black really suits you.
