Young and trans and treated

This is my first time on this site in a long, long time, as I previously just lurked, but something is on my mind that I had to go so far as to register.

In today's climate it's a whole lot more common than ever before to 'figure out' you're dysphoric and/or transgender, and on average that seems to happen earlier, but how frequently does anyone actually receive gender-affirming treatment as a minor? It feels like despite having grown up with community and support, I'm one of only two individuals I know even with that extended family and community support who received treatment of any kind besides therapy before my eighteenth birthday.

I'm an adult with no regrets, now, but I feel some weird... survivor's guilt, almost, around having had the opportunity and resources to transition when either disapproving parents or a lack of medical access barred almost everyone I knew (some of whom are still waiting, 6 or 10 years after they came out, I'd only been out for 3 when I was referred and my clinic initiated treatment) from the same.
