@Littlemissdan Not much more for me to add on here, as many posters have already given some brilliant advice... But you do have my sympathy, and so do many others on here. 
There are so many sad stories on here, it's heartbreaking... 
This is a helpful thread though, because it's highlighting how many people struggle so badly with day to day life, and the amount of poor/not well off people on here are a lot more than some people may have thought, which hopefully may be comforting in some way, as people know they are not alone.
When me and DH had DC when they were smaller (under 12,) we weren't too badly off, and managed to spoil the DC a bit (and ourselves,) and go on some nice holidays. But then a couple of life events hit us, (around the same time as the credit crunch, of 2008) and we almost went under.
Suffered and struggled for about five or six years, with no-one to help. All 4 parents passed a few years before. All average/normal people, no inheritance, no-one to help us. We were alone.
We were living like Charlie Bucket and his family for several years and really struggled just to raise the money for a couple of DC's school day trips. Other issues hit too because of the lack of money. I can totally relate to many posts on here.
Fortunately, we are now in a better position financially, no mortgage, no children at home as they are adults now, and we are OK, but I will never forget being poor as a Church mouse, and regularly give what I can now to food banks and various charities. Not trying to sound pious or braggy sorry, just that I do know how awful it is when you see £3.57 in your bank account to last a week, and you have children. I also used to be reduced to tears when we got a bill that was 2-3 times higher than we were expecting. So as I say, I do give now when I can/where I can.
We are not loaded by any means. But are OK. And my heart goes out to you.
As for the 'just get an electric bike' comment, I have seen posts by @Londoncallingme recently, and she was selling a spare flat she has, and also telling us she gave up work for a year because she didn't like her job and 'fancied a break.'
So this is someone who lives in a different world, and doesn't 'get' what it's like to have a fiver to live on for a week, and to be scared to lose a few days work because your lower pay means you will struggle to even pay the rent.
Even now, my DH works in a job where he doesn't get paid if he is off, so whilst we are 'OK;' if he suddenly needed several months off sick, we would get just £96.35 a week SSP for him. So we could easily be in a much worse position within 6 months. We take nothing for granted.
Also, take no notice of the muppets saying things like a 'TV is a luxury.' Nonsense. Even if a TV is not necessary for survival, it's essential for many peoples well-being and mental health. Ditto the internet. Keeps people in touch with the real world, and also MANY things are online now, and you NEED the internet for a lot of everyday things. Also £8.99 a month for Netflix is fuckall. People spend more than that on a packet of cigarettes!
As a pp said, are 'poor' people to have 0??? Let them lick the leftover food out of the bowl of next door's dog, and suck the gravy off the tablecloths in the local greasy spoon!
Fuxake. People deserve dignity and respect! Millions of people are suffering right now, and it's going to get a LOT worse before it gets better.
Hugs to everyone suffering right now. Hugs, and love, and warm wishes, and I hope everything gets better soon.
