This is confusing. You say the judge signed the agreement, but then later did not approve it. Were you being represented by someone? Adoption is a serious and complicated process that you should not be attempting to do on your own. Contact the agency that you were working with. You probably need to consult with an adoption or family law attorney in your area.
If you are being harassed and stalked, you need to report that to the adoption agency, the judge, and the police.
