Sweetie, any big change is scary. It takes people out of their comfort zone and into the unknown. It would be a bit strange if it wasn't scary. There's a whole lot of thoughts racing through the mind. "Once this is out there, it's out there and I have to deal with it!", "What will people think?", "What if they don't understand?".
It's scary because a big part of it isn't how we feel. It's how other people will feel. We already know how we feel. It's putting a degree of trust into other people to not be jerks. And yeah, that's a big thing.
Believe it or not, though, the first step is often the hardest. It's the one which keeps a lot of people from realising themselves. That first step can often feel like standing on the edge of a cliff and looking at your parachute, thinking "If I jump, are you going to open?"
It's one thing to know yourself, it's another to get that out there to the wider world. To make it real. But you've taken that step, sweetie. Be very, very proud of yourself. You've done something which takes a huge amount of guts and self-belief to be able to do.
If you can do that, you can go the rest of the way.
I believe in you. Keep going. *big hugs*
