I made at least one stupid mistake, maybe two.
I installed WordPress onto my host's server, but it installed into mydomain.com/wordpress. I didn't realize this was a problem, so I set the whole thing up, which took hours. Then, when I was ready for it to display at mydomain.com, I went into Settings in WordPress, and it asked where I wanted WordPress to appear, so I put in mydomain.com (it used to be mydomain.com/wordpress). Well, after I saved, I realized I was screwed, because my wp-admin disappeared. Now I can't find it anywhere.
I called Godaddy and they just said I maybe had to reinstall WordPress, but I don't want to lose all the work I did. Especially over one stupid mistake.
Where do I go from here?
