Please help me get some food.

I'm a partially sighted stroke and cancer patient, currently going through a disability benefits appeal. I have no money and my overdraft is maxxed out. The next food bank appointment is 30th Sept, and I have nothing to eat until then. I already haven't eaten in three days. I've tried everything, olio, churches, checking supermarket bins, etc. I'm desperate. I even tried selling my prescribed medications online on another website but got banned for that. I have nothing else to sell. Someone please help.
