Can I sign my parental rights away in Boise, ID? Does this erase my past due child support?

My daughter is 15. I have fought for years to have partial custody of her. I've supported her in everything she does with sports, school, ect. My ex doesn't go by the guidelines of the custodial contract. I've called the police because of this. They say there is nothing they can do I need to file " a contempt of court" for each charge. I don't have an attorney and I can't afford one. Each charge costs $ to file. My daughter never calls, never comes over. They don't go by the paperwork. I am now over 9k behind in child support. I have other children that live with me and my current wife. It's ruining my credit, my drivers license is suspended, I can't fish or hunt, I can't buy a house , nothing. If I file my rights away ( since I don't see her anyway) will this clear that debt and my obligated child support payments? It's $480 per month. I make 22k a year
