Okay, so panic over.

For anyone else looking for the solution, here's how I got home:

In survival mode (so I could search through Too Many Items) I found the portal block (search for 'portal' - it's the purple part of a nether portal).

Place on ground. Stand in/on portal block. (Doesn't matter that it's only 1 block high x 1 block wide, it still takes you to the nether.)

I appeared in the nether where my portal had been, and when I went back through the same portal, I ended up in my home world.

I'm not sure what would happen if you had not placed a nether portal anywhere beforehand.
