Sorry 😂 this is bad but funny. if you have run the php artisan migrate:fresh --seed command, it has wiped out all existing data in your database and seeded it with new data.
it's best practice to always make a backup of your database before making any destructive changes, ie running migrate:fresh.
Reach out to your hosting provider as soon as possible. There is a chance that they have backups, but not forever (backups gets deleted after a bit of time)

you can connect with hosting provider for that,
also remember one thing in your project always set up backup file.
laravel provide cron functionality you can use that to take a backup everyday
