Food bank ought to be your priority- go and see your GP or practice nurse- they can put you in touch. Why was your ESA stopped? It's usually the case that if your ESA stops then you can slide over to JSA- do you know why this hasn't happened. Go into your local job centre and ask to claim JSA or if your Dr is giving you sick notes make an appointment with them to discuss your ended or suspended ESA claim. I think if you make a new claim it is likely to be PIP but not entirely sure what's happened to you without more info or to what you might be entitled, but certainly the first step is your health, so see someone who can help refer you to a foodbank.
