It was my birth. I was born very late, blue going on black, and things were so bad that my mom didn't have a very good chance of survival either. I used to wish I would have died because it would have spared me a lot of misery and anguish. Most of it (I actually have several problems, such as bowed shins that lead to life long problems and what has been a non-stop marathon of knee injuries since I was 17) was due to the fact I was born male but have always identified as female. And I hated life back then when I was trying to live as and be male, I was a miserably wretch, things weren't good for me, and not having survived child birth would have spared me all that pain and would have been easier than killing myself. Overall, I didn't care about life and wasn't really concerned about things like consequences.
But ever since I just accepted myself and transitioning, I don't think that anymore. I won't pretend things are perfect, but few things in my life are. I'd love to have the healthy knees a 32 year old would normally have (or a 25 year old, or 17 year old, or an 8 year old), but I don't so I treat what I can to help things as much as I can. Tylenol helps to ease some of the pains. So does Premarin. I'm also autistic, and no matter what I'll never be a normal nuerotypical person, but I'm constantly learning ways of better blending in.
Then why should it not be compared to a sex reassignment surgery?
