What is transexuality?

So as an indirect result of a party I went to, my internal clock is haywire and I'm up at 1am. Clown'll eat me etc. etc.

I almost got into rant mode on a trans mailing list today. It was a rant against psychology. (no I am NOT a scientologist) It went on about how I feel that psychology, along with psychoactives, are forcing us to bury or drug away parts of us that have been tolerated by society since the dawn of civilization. Said parts of us having both negative and positive qualities, and how I felt we should go back to learning how to channel/control it properly as they did in the late 1800s and earlier.
(now to be fair, psychology has become important because our society has become a welfare state. if we don't keep the misdiagnosed who need to just learn self-discipline from dropping out of the workforce, our society will crumble under their pressure)

After writing that, my mind wandered further. I'm not going to try and claim mental disorders exist -- they do, but not in the scale that we diagnose them today. That said, I'm starting to seriously question if transexuality is a mental disorder.
Consider this: I had the intense urges caused by the wiring of my brain and my body not being the same. At first, it appears to be a mental disorder, but I contend that it is actually a physical disorder that manifests itself mental disorders to the outside observer, because they can't comprehend the physical realities of it. Depression is a good example because we all pretty much get it from this wiring/actual situation mismatch. But depression is not limited to this particular situation. Other disorders can result from situations surrounding the physical disorder and the means necessary to fix it along with society's tendancies as it is today. Paranoia and agoraphobia are two common examples.
I'm not really sure there's such a thing as GID either under these circumstances, though GID would be a great blanket term for the individual's inability to cope with the physical disorder, and the mental disruptions that come with it.

For a mental disorder to be truly a mental disorder, it needs to persist in an undrugged individual for the rest of their lives, though it can be buried, perhaps even permanently, through the individual's self control. Trying to bury transexuality has yielded poor results, but getting things put in their proper place fixes everything. So why is this not classified as a physical disorder?

If a person is blind, or born with a leg missing, or some other physical disorder, they often show signs of awareness that something is wrong. But there's no Sight Identity Order or Bipedal Identity Disorder or whatever. The individual might end up depressed, but since everyone around them is sight capable or bipedal, they're easily classified as physically disabled.
Furthermore, a blind person gaining sight through technology or an individual born without a leg getting a state-of-the-art prosthetic that is wired to their brain (and being able to use it) who once suffered depression may very well lose said depression, unless the cure was somehow botched. (as is the case with transfolk who get shoddy surgery)

As for why transexuality is so debilitating past a current point, it's because as much as we love to deny it as a society, reproduction is perhaps our most powerful driving force, while our senses (and our limbs) are just a means to that end. Thus we're constantly reminded throughout the day, every day, how wrong things are. Stumpy on the other hand is just sad that he can't run. (though that doesn't necessarily mean he's not searching for a cure either, it's just not as advanced/mainstream as SRS has become yet)

So there's my two cents, but I have a feeling it'll inflate to about $200 when my mind finishes pondering this one.
