Thanks for writing this! I say that as an LGBTQ person who has also suffered significant family rejection. I'm not trans, but our haters often don't care about the distinctions between queer people. It's often ALL objectionable to them.
Something I'd like to point out is that (as in my case) rejection sometimes does not have a dramatic moment of truth like yours. Sometimes, rejection is a de facto abandonment that only becomes clear over time, a gradual realization announced by absence, by lack of invitations, lack of communication.
This can be in a way especially tough to cope with, because catharsis is missing.
And if you try to provide that catharsis in your head, you can feel like you're admitting that maybe you're the problem — maybe if you'd only been born "normal" ...
That's an insidious trap, though, really.
It seems to me your advice is worth taking, no matter what form family estrangement comes in.
Thank you!
