Rent Plea- Eviction Pending

I lost six months ago due to being made redundant. I have had many job interviews with no luck. I have already used the money I received from my redundancy on rent, food, clothing for my children and just general living. I was contacted by my council and told that a eviction notice had been sent out and was told that I had to pay £7000 immediately. I'm so stressed out and always panicking. I don't know what to do . I am a single mother with no family to turn to.
