People on benefits - how do you cope?

[TheGreatBobinsky]

I'm making plans to leave my relationship with my 2 children, I've used an online calculator to find out what I'd be entitled too and provided I could still work some hours at work I'd be getting around £2,400 a month total (including my earnings). Rent in my area is £1,300 on average for a 2 bed flat, I've added up council tax, water, gas, electric, Internet, subscriptions for Netflix/Disney (we don't watch normal TV so no TV licence) and food and it looks like I'd have around £400 spare a month for clothes, school uniform, emergencies, childcare, travel etc. But am I missing something obvious here? (I can't drive so that's not an issue?). I have no idea how I'm going to manage, embarrassing as it is I haven't been the one to deal with the majority of the bills etc. So I'm a bit clueless about certain bills. What about furniture and kitchen things, and everything we will need in a new home? That's if I even get accepted into a flat, I know a hell of a lot of landlords just point blank refuse to rent to someone on benefits. I'm terrified, and feel sick, but if I stay here it won't be good for any of us as things are escalating rapidly and he's very good at manipulating me, I feel like I'm going crazy I have to leave but how does anyone cope?

This is all well and good but it's not practical is it? OP has mental health and 2 small kids. She needs to find a home and then she has no furniture. Not everyone is capable of a career anyway a decent hourly rate comes with responsibility and accountability OP may not cope with that right now.

Please don't be disheartened by some of the replies here, it's par for the course where benefits are concerned and I think some posters have lost sight of the fact you are doing the very best thing you can do for your children right now by removing them from an abusive home environment.
You should be congratulated for that, it takes a lot of heartache pain and courage to get to where you are now, ready to make a big scary move, knowing it will be hard but it's the right thing to do.
You know you need to leave, yes it will be hard and you probably will be poor but it's doable.
Its not your fault rents are extortionate in many areas of the country, it's criminal some of the prices being charged and paid for by Universal credit, that's not claimants trying to pull a fast one it's landlords getting their mortgages paid off with public money.
Honestly op you can do this, everything is much nicer and easier when you're not being bullied and abused in your own home.
