Help a student get a laptop?

Hey there, I'm Kirsty. I'm a student at university and 20 years old. A couple of days ago, my laptop of several years decided to give up the ghost and - despite working, I cannot afford to replace it. I'm asking if perhaps anyone would kindly help me out in this predicament? It'd be greatly appreciated. Many thanks in advance!!

why do I need the laptop? Well, being a student, I need a laptop in order to study and to complete assignments. - especially if I have deadlines that coincide with travelling places- I.e my hometown.
