Holy cow, I've going through this for the past couple of months. I didn't even think this was common, but reading your post, my thinking has changed.
I just recently came to terms with gender identity and accepted that it's OKAY to fulfill any gender role that I choose and that it's up to me to live the life that will make happy. As a result, I've loosened up a lot mentally and feel like a different, evolving person every day.
Sometimes, I can't look people in the eye that I've know for a long time --- people in my "personal life". At school, I just put on a strong facade so I can actually get things done.
I've done a lot of soul-searching, questioning, researching, thinking, etc. etc. But the biggest test is whether you've got the courage to act on your beliefs. If you BELIEVE you're a woman, you have to ACT on it. "Transition is NOT about physical changes, it's about accepting yourself and having the courage to be yourself, whatever that entails."
We use the word "transition" to refer to gender role transition, but EVERYBODY should transition to their TRUE LIFESTYLE, regardless of their gender identity, sexual orientation, etc. etc. etc. It's the path to happiness, which comes from a life of courage to act, a feeling of freedom every day. FREEDOM is so important to the health of the human soul. If you work things through and come to terms with your feelings, and accept yourself for who you are, then you'll ultimately know what will make you happy.
I was afraid to see a therapist for a long time, but I'm SOOOO glad I'm doing it now, because I can finally let go of the shame/guilt/anguish/sadness I've felt in my life, and just be myself. Instead of locking up everything inside and shutting down, I'm getting things out and feeling better. It's allowing my mind to heal. Stated in another way, when we can let go of the past and understand ourselves better, we're free to start looking into the future and make better decision for ourselves. Just talking to someone, anyone, about how I actually feel is IMMENSELY important in allowing me to emotionally to heal.
