Tori, I appreciate posts like yours. Like you I did not identify as being "in the wrong body" until recently and for me late in life (at 59). I felt like I did not fit society, but I had lots of other reasons that were more "in my face" to blame - like being poor and moving a lot. I did not have a statistically "normal" boyhood. I did a mix of boy and woman things because as the oldest of ten I helped care for my six sisters. So every time I read someone say "I KNEW at age 'x', I have doubts. I am good at being what others expect.
I am just learning to trust that what Spacial said is so very true, "Each of us is different. There is no explanation that can deal with all of these differences. There is no explanation necessary." or possible. I know I am not what my body indicates, or what others see and define me to be. I have to look inside, not outside, to discover the truth of who and what I am. And that has taken time for me to do.
Like you at least somewhat, for most of my life I have felt disconnected from my body. It was not me, just a sometimes troublesome servant. I did not take very good care, and did not care much about how I looked - except to fit in with my environment. I was also mildly to moderately depressed much of the time.
I was sad to read you dealt with your pain by cutting, and I hope for you that you are finding comfort and healing.
