like whenever I see other trans women who don’t pass it gives me a little burst of dread
As a someone who does pass, these moments fill me with guilt and a degree of imposter syndrome as I wonder why I got to be lucky when I am no more valid than anyone else. And then that's more guilt as I then become self-conscious of something that I know so many people strive and yearn for. But these moments also prompt memories of my early days when I was absolutely not passing, and how fragile, scared and humiliated I felt.
Letting go of passing as a concept entirely is probably unrealistic for most of us, but when you have these moments of dread it's healthier to recognize your common fears, struggles and vulnerability. Don't let dread win, because you only ever notice 100% of the people you do notice. Some of us eventually live in stealth, and then have internalized intrusive thoughts from that as well.
In a sense I guess I'm saying the grass is always greener, so it's better to learn comradery with those that feel the same as you do, as opposed to using them as a yard stick for yourself. It's not something that will just click and fade away, but a consenious choice to be the kindness we all want to see in the world.
