Hello Jill, welcome to this group. As you go through your journey find a trans person that has similar interests as your own that has already done some transitioning. Try to become good friends. This journey is not always easy and so it helps to have someone else that you can talk over various trans related issues.
Not to dissuade you from this group because we are really glad you are here but a matter of note. Just a little bit of a suggestion as it relates to the term Cross Dressing. As trans girls most have been dressing our whole lives. And so we prefer to just call that dressing to keep the categories of cross dressers and transgender separate. Trans girls have always felt like we were girls and have dressed to cope with life. Cross dressers still think they are guys but for various reasons have the need to dress as females.
Of course some trans girls thought they were in the category as cross dressers and later on realized they were actually girls. And then before the term transgender became common some guys that were attracted to other guys but thought themselves to be feminine found a male partner and stopped there. And yet they think of themselves as female.
For sure the idea of gender and attraction can be very complicated and confusing. I was a year into HRT before I determined my true attraction as lesbian. So give yourself some time; transitioning can be a slow process.
