Unless Yahoo support can help I'd say that you've lost that email account. You should create a new webmail account and email all your contacts advising them of the situation.

Forward the extortion emails to Yahoo Support and ask them for help. If no dice, then what NeedKarma said.

Consider this "lesson learned" regarding ANY email from ANYONE at ANYTIME asking for account information of ANY KIND... don't ever do it, not ever, never again.
