In all my research I couldn’t find a single study, anywhere, demonstrating an objective quality of life improvement.

You're saying you haven't found any evidence and that proves there isn't improvement but it's impossible for any properly done study to prove any changes to those categories. The simple reason is there is no environment that has existed for long enough to do a comparison. It's impossible to conduct a proper study on the life expectancy of trans people if they transition at 12 years old or 20 years old because the treatments have not been around long enough and people can live a long time. Even a study that tracks suicide rates over 5 years based on treatment type takes much more than 5 years.

The only studies that can be done need to use historic data and we can't change the past plus retroactive comparisons are super dicey and very prone to bias. Remember how dead patients were added post-moterm to that COVID trial published from Egypt which totally skewed the results? That study lead to large numbers of people taking ivermectin and fueled the antivax movement worldwide https://www.medpagetoday.com/special-reports/exclusives/93658

The absence of research studies can not be used to prove or disprove something and should not form your opinions based on this. As least people aren't trying and doing it poorly then people write catchy articles about it and it creates whole industries (I'm looking at you, nutritional science).
