Hi, Ashley!
You're doing really well, from what I am reading. Anxiety over a move, or a really big life event is perfectly normal, and you are just being a normal gal. Really! There's anxiety, but there is also excitement and even joy in thinking about new opportunities that are unfolding before you.
Getting your paperwork in order is difficult, tedious, and of course anxiety-inducing. Just think of the reward at the end, whipping out that ID or check card with "Ashley" printed right there on it. Being you, really YOU! 'In your face, world! Ashley is here!'
Sure, there is anxiety in big changes, but just past that are big rewards, and your new life as YOU. Just close your eyes, take a deep breath, hold it a few seconds, and breath out tension. Breathe in your future joy, hold it, and breathe out the anxiety.
You're going to do great.
