If those two tables are missing, they are missing; something deleted them. There was database server crash, the theme broke them, something happened. Ask GoDaddy if they can restore a database backup for you, or restore a full site backup.
If you or they don't have a backup, you need to have your own backups; use a plugin like https://wordpress.org/plugins/backwpup/
Be sure you have uploaded a fresh copy of the theme you were editing, too, to fix the code errors you made.
