Im being bullied

[Onita LaFebre]

What are the landlords responsibility when there is a bully.  I live in a 3 apartment building and I am constantly being yelled at and called names by a woman who lives in one of the apartments.  Last week she pushed me.  The landlords tell me that there is nothing they can do.  I live in a rent control building.  Last year a woman who lived here for 15 years moved out because of this bully.  Now she is focused on me. Any help/advise would be greatly appreciated.
