What happens If I Lied to get a restraining order but only lied to stop a huge argument that was fixing to hap?

Let me explain it for you... back in 08 I rented an apartment... and my mother didn't have a job at the time... so I let her and my little brother move in with me... a few months later she moved her meth head ex boyfriend in on me and I had already caught him trying to get my brother to smoke pot with him... I told my mother that he needed to leave... she refused so I had the Landlord evict them from my apartment... I know that it wouldn't stop him from being a bad influence on my brother but I wasn't going to sit there and watch it happen... anyways 3 weeks later they had moved all of there stuff out of my house except for a few things that they had left there... I started moving my stuff back in and told them that since my stuff was there that they would have to wait until i was there to come and get my stuff... and my mother said that she would come over anytime that she wanted to get her stuff... so i padlocked the door so she couldn't get in... 2 days later I came home from work and the door was wide open her stuff was gone along with most of my stuff she had broke my lightbulbs all over the house and dumped my clothes in the middle of the floor and poured trash all over them... and then she wrote **** YOU really big on the wall... she also took the face off of the thermostat and cut the wire it was sparking when i walked in... come to find out three days earlier my family had come down to talk to her... my aunt called her a liar about her faking to be pregnant which she did... so my mother chased her out of the house trying to beat her up... So in order to stop a big family dispute before it even started I went to a lawyer and asked about a restraining order... But when I filled out the paper... i put in there that she had tried to kill my aunt and that she had threatened to kill me... she didn't threaten me of course and she wouldn't have killed my aunt... i know this but i wanted to make sure that i got the restraining order... so i put it in there just as a fail safe to make sure i got it... I never had to tell the judge this it was just on the paper i filled out at the lawyers office... and my mother didn't contest it so there was no real court hearing just us going before a judge and him telling us about the restraining order... and what it meant and what we could and couldn't do... now its 2011 and we have made up and everything... my mom isn't a bad person she just has a bad temper and she isn't a druggie or anything but she was training to get a job at a pawn shop as a manager and the background check shows this restraining order so she can get the job unless this is off her record and the only way to do that is if i tell them i lied to get the restraining order... so what can i do?
