Lost website- Please help!

I have had a WordPress website for almost 10 years that is hosted by a third party (godaddy). The website is harrietmagpie.com

I went to view my site the other day and externally it asks the user to install WordPress. When I logged into WordPress to see the issue on the back end it seems that the website has disappeared. WordPress doesn’t recognize that I have a website. Similar to a recent poster, on any PC or mobile device we get screens asking us to install WordPress.

I haven’t done anything to delete the website and would be devastated if my site is lost for good.

Pleas help. Any advice would be greatly appreciated!!!!!!!
