I'm having problems getting an Apple ID. [View all]

I apparently need an Apple ID to access my Icloud email on my desktop computer. I get to the field in the application where it asks for an email address, and I enter my Icloud email, and it says I need a different email from my Icloud email.

I don't have another email other than my Icloud email.

"Your Apple ID cannot end in @icloud.com. Choose a different email address."

I have too many passwords and things to keep up with now. The last thing I need is more crap to try to remember where I wrote something down. I didn't want an Apple ID in the first place, but I'm stuck.
