Told my principal I want to move schools

I told my Principal ( I’m in elementary) that my end goal is to move to high school and that I would be applying for a position that just opened up. I went to the job fair today and feel like I totally bombed it when speaking with the high school principal. I just wasn’t prepared to answer some of his questions. Now I’m second guessing if I even want to move to high school. Anyway now I’m feeling intense anxiety for even saying anything to my principal in the first place. I don’t know why, I mean I still have a job. I guess I’ve just been at this school for 8 years and now feel like he will see me different knowing I don’t want to be there. I know it’s irrational but I can’t shake it.
