I agree also about retaining a lawyer. Whether you are in agreement w/the terms and conditions that he has proposed or not, using a lawyer is the best way to go. Whatever you learn in the lawyer's office, please do not share it w/him. Knowledge is power and the more you know about your legal rights, the better.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
