Fair enough, honey! Well, you won't find anyone judging you here.

Hrt will, over time, slightly soften facial features, but many TG eventually need or want some kind of facial surgery to further that process. HRT will also somewhat soften and feminize body shape as well. That you are young works dramatically in your favor, as skeletal issues have not fully hardened yet and you may see, if you continue, some reshaping in the pelvic area. The principal changes will be in your breasts (which should change a lot, especially given your age ....jealous!) and in your emotions. You can expect emotional change to take place over time and be prepared for sudden outbursts of tears at unlikely moments. It does not happen to everyone but it does occur a lot.
Hrt will not, on the other hand, change everything.
It will not change your voice. This can be accomplished, though, through physical effort and/or by surgical methods.
It will not reverse advanced hair loss in the scalp area, though it will, in time, greatly diminish the growth of body hair. It will not end facial hair. Facial hair can only be stopped through laser or electrolysis, both of which are costly.
Most of all, Hrt will not solve life problems, and in fact can make existing problems more complicated.
If you truly are TS, iT will bring you a measure of peace and allow you to work toward becoming the person you feel yourself to be inside.
As a further reference, I suggest you check out crossdressers.com. It is not a pick up site, nor a meet market, but rather a well run community support site for both cross dressers and Ts girls of all ages and needs, and includes a purely TS sub forum where you can obtain support and advice from many girls who are in various stages of transition. If you do, though, I would advise against mentioning herbs, as not only do they forbid that, but also there are many there who, from ignorance, are quite opposed to the entire concept of herbal HRT. None the less, it is still a very valuable site.
Ask anything, honey. People are here to help each other.
