Hey some of you guys don't know how good you have it. I'm 189cm and 58kg.

Yeah, I know I need to eat, but at 19 and just about to start university I can't really afford all the expenses. How do you guys (students) cope? I mean there's a shitload of food to buy, gym membership, protein. Very frustrating lol.
Btw is 3200kcal a day good enough to see gains (of any kind)?
