I need to do this homework, it's only 300 words, but I'm burnt out on focusing and can't focus any more

I want to go get food to help me focus but
1) we're really tight on money and everything I can think of near here is expensive-ish
2) I feel bad when I get take out and Lottie doesn't
3) I'm using the uni wifi to download stuff, and I don't want to cancel the downloads
4) Food is a ten minute walk away, which means it adds an extra half an hour stay to how long I'm here at uni
