Parents finally responded to the letter. While the response wasn't what I was dreaming of, it wasn't the response I was dreading either. It's a starting point.
I'm out, my parents know, my in laws know. Progress.
It was so busy today at work that I just barely had time to process all of this. Now that I'm home it's been settling on me more and more. I've been transitioning for five months next week and this is the most real that it's felt. I'm becoming who I've always dreamt of being. And my family knows.
Whether or not they'll be supportive in the long run is up for grabs, but I feel like I've crossed my own Rubicon.
