I appreciate your concern about the welfare of people of transition and our high rates of suicide. I looked at the NIH document and saw it study was from 1973 to 2003. Not totally out of date, but there is even newer data.
People who get treatment do better than people with no treatment. Living in the wrong gender is like being in a room with no windows or doors and the room is on fire. Remember when people leapt from the World Trade Center after the attack knowing they would die? When there is no hope, people will end their lives. As a trans person this is the closest I can get to trying to give you a visual of what GID feels like.
Those of us who get treatment are happier. Personally I am happy beyond belief. Like Orlando says in the Sally Potter allegory about transsexuals movie, “I’m so happy I think I’m going to faint.” Society still persecutes many of us and this is why some people can never quite escape from that burning room.
However, for those who live more or less cis lives post-transition, the relief is enormous and long-lasting. For people who live trans, it is also much the same. The key is treatment and stopping puberty of the wrong kind, and giving the breathing room for the sufferer to be old enough to understand what the person needs to do. Yes. You are right. Some people will not want to transition, but some will. Will we throw the baby out with the bathwater?
Advances in stem cell research may mean that in a few years we might get reproductive organs consistent with our genders. That will be a wonderful world for sure. There is much to hope for and it is coming down the pike.
It is so sad that people take their lives, but to stress it again, often it is because the person has gone untreated for so long and has been tossed into society’s dustbin. Addressing the dysphoria early is the key to better outcomes, not shutting the programs down.
