At my lowest, after my divorce, I left with just the clothes on my back and had to start life from scratch, I lived on £700 per month, that was paying £300pm mortgage, £100 council tax leaving £300 for everything else, running a car, bills, food etc. To cut costs I went on FreeSat TV no monthly TV bill. I only bought reduced food eg once I got a bag of spuds and bag of veg sausage rolls for 50p, and that is what I ate all week. If I made a purchase always used reward cards like nectar, tesco points, and online shop via quidco, and my cashback added up, also got cashback from credit card so double whammy on rewards. I sold almost everything I owned on ebay when times were mega tough and I got ill and housebound. Hermes courier would even come and collect parcel as I could not leave house, and had a milkman deliver milk and bread. I grew my own salad in window boxes so fresh salad pick my own in summer. It was very hard and very scary being on my own and then being ill unable to work. I survived just had to watch every penny. good luck!
