Yeah, try to give a little more info.
I'll take a guess from what you said.
Ooops. I think I deleted nearly everything.
I change the name of my files (the folder) from ******* to *****. Now my files and settings are gone. Oh nooo. How can I get them back and what happened???
Thank you!!
I'm guessing you changed the name of your Home folder?
your Home folder = where you see the sub-folders Desktop, Documents, Library, Movies, Music, Pictures, Videos, etc.
It's located at HD > Users > [your user account name]
Is that the folder of which the name you changed??
If so, try to change it back.
Mac OS X might have created another one in the meantime to "replace" your old one, which has gone "missing."
In that case, you might have to delete the new one first, then rename your original one back to what it was called.
