You've brought up a very good point, spacerace.
I do think many of my issues were caused by being trans. There's really nothing else in my past, no serious abuse, sexual or otherwise. The worst thing to happen to me as a child was being trans. But even so, transition didn't fix trans related issues like social anxiety, drug addiction, binge drinking, etc. I had thought it would. But you don't just fix a lifetime of suffering in a few months or years of having the right body, role, etc. All it did was make me more at home in my body and slightly more comfortable going out.
Maybe for someone who didn't develop a lot of other issues like I did, transition is a panacea. I wouldn't know. I am getting better, but it's still a lot of work. Once you've developed all these unhealthy coping mechanisms and conditions, they don't just evaporate along with the F on your license. It's fixed my dysphoria, but I'm still one messed up dude.
