Hello MirandaLee: I see this is your first post... welcome to PsychCentral! PC is a great place to gain support as well as to obtain information regarding mental health concerns. There are many knowledgeable & caring members here.

Ya know... I'm in my mid 60's now. And I often have to remind myself that I'm an old person not a teen anymore! I recall my father once saying, when he was in his 60's, that he didn't feel any different, on the "inside", than when he was young.

But, also, I think that many, if not all, of us who are trans regret not having had the experience of growing up as our true selves. So, personally, I don't find anything you've written to be out of the ordinary. And, as far as the difference between the terms "girl" & "woman" go, I think there is a tendency in our society in general to associate the term "woman" with a more mature person. And, likewise in our youth-oriented society, few people want to think of themselves as old... I certainly don't... even though I am.

So, from my perspective, I would say: relax. All is well... I send you my best wishes...
