My site is gone

Hi,

All of sudden my site is gone and my host says they cannot help, since the backup they have has the same database problems. I did not touch anything for months, so I have no idea what could have happened.

This is what I get while trying to repair database:

wp_users: Table ‘secanj5_wrdp3.wp_users’ doesn’t exist
wp_usermeta: Table ‘secanj5_wrdp3.wp_usermeta’ doesn’t exist
wp_posts: Table ‘secanj5_wrdp3.wp_posts’ doesn’t exist
wp_comments: Table ‘secanj5_wrdp3.wp_comments’ doesn’t exist
wp_links: Table ‘secanj5_wrdp3.wp_links’ doesn’t exist
wp_options: Table ‘secanj5_wrdp3.wp_options’ doesn’t exist
wp_postmeta: Table ‘secanj5_wrdp3.wp_postmeta’ doesn’t exist
wp_terms: Table ‘secanj5_wrdp3.wp_terms’ doesn’t exist
wp_term_taxonomy: Table ‘secanj5_wrdp3.wp_term_taxonomy’ doesn’t exist
wp_term_relationships: Table ‘secanj5_wrdp3.wp_term_relationships’ doesn’t exist
wp_commentmeta: Table ‘secanj5_wrdp3.wp_commentmeta’ doesn’t exist

Can anybody help please?

Thanks
