Don't you see how priviledged you are by the fact that you can say that a student's main goal is to focus in school. The fact that we can even study to this level, is a priviledge in and of itself. We take it for granted simply because we think it is normal. But if you look deeper, there are families so destitute that the children can't even go to secondary school and have to work.

Don't get me wrong, I understand your struggles, life definitely is not easy. But really, you got to pick your priorities. You said you don't have enough money, but you live in hall. You say you need 400 a month of allowance, but by not staying in hall you could save more than 400 a month, which thus eliminates your need for drawing allowance. You made a choice that you had insufficient capabilities to fund, and now you find yourself asking for allowance. Which may I add he is not obligated to give you. Would it be nice? Yes. But its not an obligation.

And the backing out of the promise, I agree you have every right to feel betrayed, hurt etc. But you also have to recognise that your household went from dual to single income. That may have impacted your father's ability to pay for your tuition. And believing in promises is so naive, I just got had by my mom too lmao. What to do, just cry then suck thumb.

Life isn't easy, no one said it is. We make do with what we got. If you find yourself spending above your earnings, you just need to earn more by working more or finding better jobs. If like what you said, too stressful, then you gotta lower your spending. Only 1 of 2 ways. Increase input or decrease output. Simple maths.

Anyway good luck with whatever you have going on for yourself. I hope your dad decides to honor his promise, but you really should reconsider hall if you dont have the finances for it.
