Fighting With Facebook Again

I've been having troubles trying to log into my own account there ever since last night. I've been forced to set up a second account again, just to be able to log into my real account and reset the password...and it doesn't recognize my e-mail address and password combo as legitimate despite my having set it up myself. Repeatedly.

When I try to recover my actual real account, the system keeps diverting me into the second account...which I did not want to create, let alone maintain in the first place.

HELP!
