Why is being a student so expensive?

I am eating noodles for every meal because my tuition just took all my savings. I have a huge business degree paper to write but I am so stressed about bills that I cannot focus. My laptop is also starting to die and I cannot afford a new one right now. The pressure is getting so heavy that I almost started looking for an affordable assignment service just to get some help on my research. Does anyone else struggle to pay bills and study?
