Editor not showing website??

I feel super silly but my marketing manager and I had to part ways pretty abruptly. I now have access and power to edit my site but when I'm logged in I can't find my website at all in the editor.

What shows up is only the default new website template. I'm a little panicky because I do need to make some changes but I can't find it anywhere. I checked just about every tab that makes sense on the editor home page. Does anyone have insight on this or does this even make sense?

I did double check and my website is still live! I just don't know how to get to the editing.

Thanks so much in advance for any tips! <3
