My neighbor is constantly spreading rumors that are untrue and calling agencies on us what can i do?

we are a family of 6 living in a decent but not perfect neighborhood. she has had issues with us since her son and my daughter broke up. he says they never were a couple but he showed me the ring before they were a couple. they broke up cause my daughter wouldnt perform favors. they r always calling code enforcement and the pound on us but everytime they come out they ind nuthing is wrong. are there any laws on what they r doing to us? we feel so uncomfortable in our own home cause she wont leave us alone.is there anything i can do? she even has camera's on the top of her storage bldg aiming towards my house so i dont even like my kids swimming in the pool. please help if you can we are in bartow county, acworth ga. we cant afford an attorney.
