Hi Damara
You say you are mostly living as Damara, but not all the time. What are the times when you are not?
This is a common enough observation or complaint on Susan's - living it, but not feeling it. As I commented on other posts (one of Suzi's unless I'm mistaken), I really don't know if happily comfortable cis people feel their gender role. They just
are. As I see and discuss with more people here, I think the issue you discuss might be an
artifact of our trans condition, understandable enough, perhaps, as we move from one gender role to the other.
I think it's nuts to see yourself as a "fraud human" - you're a human human who's currently changing gender. Not common, but definitely NOT fraudulent in any way. We all have our doubts from time to time, but I'd challenge anyone to come up with a definition of someone being a perfectly female female, and especially, how they feel as one. OK, we have to fix some things with HRT and surgery, but that's how our particular cookie has crumbled!
The rest, as I see it, is fundamentally self-image, and also how people perceive us. There's a saying out there: "If it looks like a duck and walks like a duck and quacks like a duck, then it's a duck." You just need to let your inner duck emerge. Give her time...
And from your avatar, there's nothing wrong with your external duck

Hugs
Julia
