lost workspace and pages

Hello,

Somehow it's ended up that my single account has two universes: in the first one there are my own documents that I've been collecting, and in the second one there's access to shared pages. And for some reason, depending on Confluence's mood, I end up in one universe or the other.

The problem is that I've now lost access to the page where all my knowledge was stored — it's awful. I don't have the special link or anything like that saved anywhere.

What should I do?
