Make no mistake: gender dysphoria is real and you are not delusional and by trying to downplay our emotional need to express ourselves we are making a mistake.
At the same time, I am very realistic about what I am doing to treat my dysphoria and understand that I was not born physically female. However, the idea that gender identity is established exclusively through birth genitalia has been pretty convincingly debunked which means that gender and its expression should be left up to the individual and not to society. But unfortunately, we live in a world where disobeying the rules leads to suffering through persecution.
Transition is one way to treat your “gender expression deprivation anxiety” (thank you Anne Vitale for that wonderful term) but it is not the sole method. However, denying that the feelings are real is a recipe for depression and unhappiness because gender dysphoria is serious business and is most definitely not self-inflicted. It is also not, as I once believed, a weakness of character and at some point we need to face the stark reality that our lives will not be conventional. But that does not mean we cannot find a positive spin and make it work to our advantage.
Take it from someone who lived with the discomfort of denial for many years and treat your dysphoria in a way that works for you.
