Need Financial Advice!

I am a victim of constant consumption. I'm a small town girl, still a student, living in a big city on my father's money. Sometimes just to match the level to my friends I overspend. These days it has become more frequent and I'm always in debt. I have no saving skills, I end up paying all the bills even when I want everyone to split. Please give me some ideas I can save more and spend wisely.
