I agree with Ms Grace. You should definitely consult a professional. That said, I would offer the perspective of someone who suffered for decades from similar self-hatred.
Early in life, I had always defined victory in terms of conquering my gender. "Man up!" "Be grateful for what you have!" I tried everything. Nothing worked. On the outside, I was a huge success. Inside, I grew more and more miserable.
One night, after a particularly deep and dangerous bout of depression, I realized that I needed to redefine victory. Victory lay not in conquering my gender, but in learning to accept it - with grace. With that realization, I walked into daylight for the first time in my life.
It was like there was a person inside me, a little girl that I had stifled and abused since she was born. I never allowed her a voice. I never nurtured her or allowed her to experience love. I made her feel worthless.
The world can be very cruel. But as it turned out, I had been my greatest tormentor. That was a painful realization.
It helped me to think in terms of a helpless child within. If I wouldn't stand up for her, who would? My mantra shifted from "man up" to "take responsibility for this helpless person".
It took me a year or two to earn that child's trust. I had to convince her that, from now on, she could count on me to speak up for her, to take care of her and, most important, to love her. If you cannot love yourself, all the love in the world from others counts for naught.
Once I earned her trust, I basically became an integrated person again. And I was ready to pursue my superficial transition in earnest. [I hate the term to "transition". All I am doing is to give the person inside me the visibility and affirmation she deserved all along.]
I am one. I am happy. And I finally understand that, no matter how the rest of the world treats me, I have an obligation as a "parent" to love that person inside. It is the most important thing I can do.
When you don't, you suffer from a double hatred. You hate the "child within" because you are ashamed of who and what they are. And you hate the "parent within" for being ashamed in the first place. It is a difficult hole to crawl out of - but worth it!
