Lost Word Document and cant find it!!! I saved it but it ISNT there!!

[APAV]

Please help i have no idea what to do. I have been working a document for like 12 hours now just finished it was about to email it. i have been continuously saving it all day and I saw that I did. I x'd out of it on accident, and it didnt ask me to save, it just closed so it should exist!. Now I can't find it! I have a blank template, or the previous version i downloaded from my email so it must be somewhere else. I have searched my whole computer and it just isn't there, and I know I saved it. This is not possible. 12 hours wasted? I have no idea what to do now.. I cant find it on my computer and I can't pull up the recover panel help!!
