Keep in mind that when you sue for securities fraud, you're suing the brokerage or investment company, not a particular broker, even if they're the one who broke the law. Don't let a sob story on anyone's part slow you down; it's up to the company to keep a tight rein on its brokers.
Don't feel guilty about the fact that you've lost money through your broker's malfeasance. You're the victim and were taken advantage of. The bad guys should be punished, not you -- so take them to court, where their bad deeds can be made public, and you can get your money back.
