You should consult an attorney. It's very possible for you to find a lawyer who would be willing to take your case on a contingency basis (meaning no attorney fees unless the lawyer gets you something). Generally speaking to establish a prima facie case of legal malpractice you will have to prove that your  attorney was negligent,  that the negligence caused you to lose your case, and  had the attorney not screwed up, you would have won your initial lawsuit.
The questions is: how was your attorney "inept"? If she blew a statute, then it's a pretty easy case. You just have to start calling lawyers in your area and walk them through your specific fact pattern.
