I’m not sure how the comments disappeared, but the only way to recover those is to go revert to a previous database back up. Hopefully you have one or your host does.

I do have a backup. A week and a half old so that’s not bad.

No that’s actually really good. Good luck and don’t forget to upgrade to the latest version of WP.
