deleted blog page or user from wordpress or ftp

Hi guys, Please help, Im new to wordpress and ftp. I deleted my site from my Filesilla (ftp), but i deleted my blog page and files by accident. I can’t seem to get on my blog page now – wp-admin or log in with my log in on wordpress.com or my website as i usually can???
Have I now deleted my whole user on wordpress.com or .org and do i need to re-set up a new account or can i find or recover my original blog page??
I wanted to redirect my hosting web site to my blog page (as i had done before) again but now i seem not to have my or access to my blog page?

Please help???…..

Thanks Natalie
