Yeah, finances can be pretty personal. I for instance take issue with others (such as my mother) telling me what is essential. For instance if you restrict spending to the point where you feel like you have no life, that isn't worth it. The books I've read about finances advise to always give yourself an entertainment budget. Also many people's debt is not due to frivolities but to making rent, buying food and clothes, and so on. Rents are ridiculous in my city and for your rent to be 1/3 of your income you would have to earn far more than most people.

I hope you can find a decent job soon. Then you can focus on getting somewhere with cheaper rent.
