If you don't have a lot of money and are sick -- what do you need?

My Girlfriend has contracted a bad cold from someone else who lives in their home (she doesn’t get out much and has little immunity for that reason). Because I was with her and we kissed the night her symptoms began, I’m thinking I will get it in a day or so. I am diabetic and have a much harder time getting well, though have fairly high immunity due to being in public often.

Anyhow, neither of us are even able to make our monthly expenses (expenses exceed income)— I am trying to provide whatever foods, drinks, meds, or whatever. From times past, when I was better off financially, I know that sickness can really break the budget. Therefore, what do I REALLY need to help her, and then me, through this illness?
