I do think there's something else going on, I understand we don't know what the procedure is or anything but £500 is more than enough money for two months of food, bearing in mind if she's staying in a hospital she probably won't have an oven/hob.
I feel like she should put more info on the gofundme so people can actually understand it? "I'll keep it short and sweet" Well maybe you should elaborate? If you're gonna ask people for their money? I mean ffs £315 is enough more for food for one person for a few months, plus extras. I don't get it, it seems like she's very much just on the beg.
