Ebay Dellima. Help Please!!!?

[Joe]

A few months back I clicked buy it now on an item without knowing that I couldn't take it back. I know it was stupid. I didn't know what to do at the time, so I just closed the account down. Now though, a few months later, the item still hasn't shipped, so I am I still required to pay for the item? Now, I tried paying, but I wasn't in the awaiting for payment section. Thanks.
Also, will they do anything to me? I just want to be sure. I know I was stupid.
