Can you appeal a restraining order that has been granted by the judge for five years?

my ex-wife completely fabricated stories against me, telling that she was battered and that one morning, i broke the glass of the window of her car. she showed no proof except for a receipt that she had her car windows repaired. i didnt really do it, i was fast asleep during that time but i wasnt able to show evidences except to tell that i was sleeping with my kids and that i had to go to work at 4am. i mean, i dont really have any motives for doing that because i was the one who left the house to be away from her. i have receipts that i even changed my telephone number so as not to have any communications with her. the problem is, i can't speak myself that much and i got really nervous to explain my side. she's really giving me a hard time and i want peace of mind..
