What is there to do socially for recreation on a Saturday night in New York City?

I live in Brooklyn, New York and I don’t have many friends and I am always so bored! I would like to have some fun/ recreation/ social times when I am not working. Money is not a problem. I work hard all week as a nurse. Any suggestions on how to make friends and have fun for a 40 year old lady.?
