Where to live in Chicago? 21 year old female new to the city.

Hi I am a young female, actually just turned 21 last week. I am looking to move to Chicago around May. At first I was looking around Rogers Park as I assumed it would be the cheapest. Though after looking around a lot over the past month I have learned if you look enough you can find a steal in most areas. So far on my list of places I would live are Edgewater, Bucktown, Logan Square, Uptown, and Rogers Park. I'm not really all too sure on where I want to be though. I am single and have no children. My monthly income would be about 1600. I own a car but could leave it with my grandparents if it turned out to be that unnecessary. I don't mind a long commute as long as it is safe to get onto the transportation. My job would take me around Chicago though I would mostly be around River North if that makes any difference. It would be nice to have easy access to some nightlife though I could always take the train. Any advice? Thanks!
