CosmicJoke, I'm so sorry for the pain you've been through.
I've experienced something similar, when I came out, some people walked away.
It hurt.
And I know your connection lasted over a decade, which makes the grief even heavier and more complex.
It's okay to mourn that kind of loss.
But I've also learned that their absence creates space for people who align with who we are.
What's helped me is stepping back from cisgender spaces and connections that can't, or won't, accept and understand me, and instead seeking out community and connection within the LGBTQ+ family.
I hope that helps, even just a little.
