Did this overwrite my EMMC?

It's now stuck at the CM logo.

What should I do next?

Sounds like you were wanting to run CM on SD. If that is the case you do not use ROM zips from CM. They are designed for emmc. You must use the ROM zips from verygreen's thread.

To fix your stock, go to my HD/HD+ CWM thread linked in my signature and flash the plain stock zip from item 6. If it still does not boot right, go back to CWM and do a factory reset.
