Thankfully I never got to the point of needing to try and use a foodbank but it was close. In Surrey of all places! Long-term illness lost me my health, my job, my savings, everything. I'm incredibly grateful to even know there was an option for food if it had gotten that bad, thankfully after over a year of looking for anyone who would accept a disabled tenant I found a place, borrowed money, and moved.
It can happen to anyone. Took me over a year to 'go on the sick', from applying for PIP to the humiliating and mentally and physically brutal interview to essentially beg for help. Anyone who feels it's easy to get benefits or referral to a food bank should go ahead and try it. Ever sat in a room with a random physiotherapist and had to describe in detail how you wipe your own bottom? The best part was getting tutted at when I cried, really helped my mental state.
At my lowest, having lost all my savings paying a rent I could easily afford while working full time but was very difficult to move away from once too ill to even dress myself, I discovered I could exist on about £3 a week buying nothing but tesco cream crackers.
It can happen to anyone, suddenly without warning or something inevitable however hard you try and fight, circumstances end up with you needing that help and it's great it's there. I'm sure there are people who see benefits as the easy choice, just go on them, but I have to say it's been harder to get help than to get any job I've had! And that's for disability, supposedly put in place to support um the disabled.
