Hello Raye,
I do empathize with you I grew up in an eastern Tennessee mountain family (Knoxville was like NYC to us). I know from personal experience it can be hard to deal with your problem in environments like that, but you should realize you are on your own now and only you have to live your life and suffer with GID, if you do not seek therapy/treatment you are the only one who will suffer, not your family, not your friends, not your neighbors, only you!
If you are worried about the whole "HONOR & PRIDE" thing like a lot Tennesseans are force fed from the womb then let me tell you in your situation don't, your GID will not get better it will only get worse the longer you leave it untreated.
I am telling you this because I was worried about the same things that you are worrying about when I was your age and all it did was cause me to delay treatment based on fear (which was a HUGE mistake). I reckon you should find yourself a good therapist in one of the larger cities Knoxville/Nashville, even if you have to make a trip it will be worth it!
As far as your bone structure is concerned yes it can be depressing at some times, I am very small (short & thin) but I have very long hands (not man hands, but my fingers are long) I was always so worried about this, but when I brought this up my therapist said the most amazing thing "So what, you are a woman with long hands", and you know what, she was right! I recently seen my mother & brother for the first time in years and I realized that my mother has the same type of hands that I do (my brother's look completely different typical man-hands) and her shoe size is the same as mine even though she is several inches shorter! So don't worry so much about the size of your hands/feet this tends to be something that other trans-people bring up more than cis-person. Immature cis-girls may make fun of big hands, but that doesn't mean they will immediately assume you are trans.
I hope this helps, btw where are you from?
