I Can't Sign My Name

At my closing yesterday all the document had my name as First name, Middle Init, Last Name. My lawyer told me I had to sign all the documents that way. Now, since about my first year in college I've signed my name with just my first and middle initial and my last name. And when I actually write something on paper I print. I don't write in cursive. Ever! It became a bit of a running laugh during the closing as I literally struggle to write "Eric" in cursive. I guarantee ever single signature is very different and most of them are completely undecipherable.
