You could have a look here for a few thoughts that might help:
there is a brochure for the british NHS called doh-transgender-experiences.pdf ...
only thing I don't like is on page 7 talking about stress... many experience relief...
it states biological causes, and that its a spectrum... so it might be easier to explain to others, and it might help with self acceptance...
You might think about visiting a lgbt center if you want to... there might be counseling there, and support groups...
