and holy FUCK if you are on the fence about it, just DO IT. I had a really rapid response where I knew within a day that it was the right choice, and that came at the tail end of three or four years of intensely debating if it was "too late" or "still worth it" or whatever.
It was incredibly, indescribably worth it. It continues to get better all the time. I give less and less of a shit that I waited as long as I did the further I go. It has been a hard year and I've felt better than I ever remember feeling.
I'm in my 30s and I used to think I would regret not starting in my 20s/teens/not starting sooner. Honestly? It's hard to regret any of that now. It just... Doesn't hurt like you think it would to look back. The downsides you imagine are greater than the ones you'll actually face.
A particular friend who was unabashedly trans before that was any kind of mainstream okay is much of how I was able to realize who I am. My hope is that anybody who needs to see this, sees this.
