Cost of living in Delhi as a student?

A partial drop student here, wanna move out of my town to delhi cuz ive had enough in my hometown. Had joined a college here last year because i couldnt get into DU and in panic of not getting a college and getting a drop year without my will i took the wrong decision. After months i realised this is not where i want to be really and i wanna move out. Had arguements with my dad for the first time in my life because of it but yeah he agreed for a drop and a delhi move. So yeah i have already wasted quite a sum of money here and i really wanted to know what are the finances of living in delhi as a student?

- PG or Rented Flat preferably

- Gym fees

- Travel expense (I like travelling so this could bite me)

Also is it possible for a student to get a part time job in some mall, restaurant or shit and manage it with everything else?
