Yes, the early stages of transition are worrying. I remember: "Will my wife leave me?", "Will my neighbours come after me with pitchforks and torches?", "Will my wife leave me?", "Will I be safe?", "Will my wife leave me?", "Will people laugh at me?", "Will my wife leave me?". Etc., etc., etc..
I am not completely done with my transition - still waiting on GRS - but the biggest, scariest part is done. I am out, and have been full-time for over a year and a half. And yes, the worry is gone. All of it.
My wife didn't leave me; my neighbours didn't attack me; no one laughts at me. Life is good. I get to be me all day, every day. I don't have to pretend. I can like what I like. I can look pretty. (With clothes, anyway. Face, not so much, but I am not complaining.)
I have some remaining irritations. They are not worries as such. I am still waiting on a letter that will allow me to wait to get onto the waiting list for surgery. I am still waiting for my official gender change so that I can get all my ID changed to the proper gender. But I know that that stuff will happen eventually, and it doesn't affect my day-to-day existence.
I think you are asking whether this journey is going to be worth it. Everyone is different, of course, but from my point of view, the answer is a big YES!!
