You say you need not to be isolated from your family but also that there is nobody will take you in? Why is this?
Not sure you have it correct with the effect on UC have you double checked this? NOT with dwp (who can and will lie through their teeth!) I would advise you check with your local councils welfare rights advice dept that's who I use for good benefits advice
Also it would only need to be temporary surely until you find somewhere else?
Also, have you spoken to shelter? They're very good at this stuff too, they can even represent you legally
What is your concern re a refuge? It's a temporary solution and will give you the time, space and support to sort yourself out
They always tell people they could put them in a place far away and you have to put your foot down with the council
I suspected as much, I've been told all sorts of rubbish when I've been homeless.
Please call shelter and welfare advice tomorrow, I strongly suspect they will be a massive help. All is not lost you don't have to move back in with ex.
