How can i sue a lawyer for malpractice after the statute of limitations has expired?

I hired a lawyer to handle a traffic infraction case. I have a CDL and didnt want a speeding conviction on my driving record. My lawyer told me that it would require me to pay the fine and attend two driver training classes,which was fine with me.My lawyer didnt go to court for me and i was convicted of speeding and failure to appear. She then withdrew as my lawyer and threatened me with a restraining order if i ever contacted her office again.This is the reason i never persued a lawsuit, I was intimated by her and thought it better to drop it. I have been turned down for jobs due to this ticket, my wife and i have seperated and are divorcing , my house went into foreclosure and my business has failed due to the increase in my insurance costs. All this was explained, to my lawyer,would happen with the exception of my marriage, when i retained her.I regret my decision to not persue a lawsuit very much. The damage caused by her negligence and incompetence is severe and on going. Help
