Can you close the document without saving your changes?

I have a 500-page document. All endnotes were bracketed
example: [29] because I did not know how to use
superscript. Then, I read how to use it on this site.
It worked, but all the numbers withiin the text jumped up
too. (All the text moved,too)
Sounds like you selected all, and applied superscript? How did you do this?
Stupidly, I then tried to
get rid of the brackets and just leave the supscripted
numbers.
And how exactly did you go about doing that?
Wrong! Now I have NO endnotes. Instead, I have
0 90-90-90- replacing every single endnote and every
single number that falls within the text! I tried to use
the Undo arrow, but it says It Can't Undo. Please, is
there a way to go back to my original endnotes WITHOUT
the superscript?
