Oh diddums, only £70-90 a week? I'm on £200 a month, which includes food, phone, textbooks etc, as well as anything "luxury" (I know my phone could be considered a luxury, but it's £15 a month so I don't really consider it that) like clothes, meals out, nights out etc. If I go for a night out, that's two days food budget, so I have to live frugally for the rest of the week.
Of course it'd be amazing to have unlimited disposable income, but really I don't care. I've got enough clothes, buying something new is a special treat instead of something I do every weekend. My laptop works for what I need it for, the same with my phone, I don't crave upgrades for either.
I have a friend who is at the very limit of her overdraft because as soon as she gets her loan through, she goes shopping and spends loads of it. Then despite being overdrawn, she still buys new clothes every weekend. I'd hate to be in that situation! Spending more money than I have scares me. And the vital thing is, I can separate what I need with what I want, and I don't get whingey if I can't have everything I want.
Edit: And yeah, I don't get a grant or bursary. The people who do get a grant/bursary have more spending money than I do; their situations end up being similar to those with a high family income. It's people like me, whose parents earn just above the cut-off point, who lose out. Luckily for me, my parents can afford to give me some money at the moment, but I'm not sure if they will next year. When assessing for grants, the government doesn't take into account multiple children, or where you live. My parents have 3 kids and live in Surrey, one of the more expensive regions of the country. We're hardly rich, and I hate taking money from them, but the government won't even lend me enough money to live off, and I can't get a job during term time.
