Mentle harrasment by senior citizen neihbour

M living in central delhi with my down syndrome child we hv shifted to this place last august 2020, by knowing this fact that i going through such critical situation of my child our neighbour who is a senior citizen lady staying alone(her son nd daughter in law are separarated by herself) creats lots conflicts on daily basis. We are not even allowed to put sheds on our window as per her, she often used to conplaints mcd and police for wrong construction being done by us whereas there in no construction or renovation is going on at my home.. Daily visits of several people from different department is hampering us a lot. Now it has become a mentle torture for me.. i cant even look after my son.. every single day people comes to visit my home and question me for my home coz of which my son gets neglected.. Plz help me as local police is also giving her priority of being senior citizen pressurrising us to stay away.. Everyday there is new issue comes with her sometimes my home sometimes it parking of car..
