I had this building feeling that it was something I wanted for myself, and it was growing for a long time as I came to understand more about my identity. I was also deeply afraid though, so I totally get what you mean. I thought that I'd have to commit all the way from the get-go, and that sudden physical changes would mess up my life.
I talked with a transgender friend of mine, and he reassured me that it was ok not to know my destination, and I could just start E on a low dose, go slow, and see how I feel. It's a lot less frightening when you know you can change your mind whenever.
I just ended up finding that the longer I was on it, the more like "myself" I felt, and that point where I changed my mind never came. It is so much easier to get started on something big like transitioning if you take it a tiny bit at a time and check with yourself to see if you're still on the right path for you.
Huh, a long faucet ad in Vietnamese posted to the Star Trek lemmy community. How in the world has this come to pass? lol
