How can I retrieve the pword for my yahoo account? I forgot the answer to the challenge question.?

Last June, I accessed my yahoo email account, & was able to send messages to my friends & relatives, then signed out. After an hour, I decided to sign in again, but could not access my account. I re-entered my pword several times, but could not really access. I filled out that portion for the "forgot your pword". I was being asked for the answer to the challenge question but, I could not remember. I created that email addy 7 years ago! Is there a way I could ask & write the yahoo staff how I could retrieve the pword? That email addy really means much to me, that was my very first email account. I had to create another email address last July, to facilitate communication w/ my friends & relatives. I am hopeful that there's a way to do this. PLEASE...! The new email account: xstn_05_28@yahoo.com. If the yahoo staff/management reads about this, I hope they can HELP me out w/ this concern. Much thanks!
