financial worries

Hi 

I've started radiotherapy two weeks ago for prostate cancer, the side effects are quite debilitating (fatigue, incontintence, and diarrhoea) I am currently signed off sick from my employment, which has led to a significant drop in income this month, and probably next month, can anyone help with advice on how to get some (temporary) financial help to tide me over, until I start 

employment again

With thanks

Tony
