Wow Ashley! What you wrote is are thoughts that have (for the most part) also been going on in my head!
What helped for me was telling my friends and my siblings. That way, I could always express how I feel without worrying what part of the duality I was supposed to present. It doesn't really take away the practical struggles like wanting to have long nails for Tassia.. and short nails for the boy doing karate.
But it helps in me being me all the time regardless of which part of me is surfacing at any given moment.... and this in turn makes the rest a bit easier.
And @Isha, you're completely right (at least for me you are)!I truly believe that by embracing both genders into your life, you will find balance of sorts.
