Business Profile - no longer have my creative cloud library. HELP!

Whan I started indesign this morning I got a pop up asking if I wanted to join my business profile or perhaps it was team I can't remeber now but it had my workplace name - I clicked yes not really thinking too much of it but now when I open creatve cloud my library has gone which is a disaster as it took me months to build and I need it to complete my work efficiently. Can anyone help please!?!
