And I think my entitlements are a bit worrying..
I work full time and earn approx 15k.. I hoped I'd be entitled to some housing benefit but the calculator is telling me not. And that I'll only be entitled to £137 working tax credits a month 
My child situation is a little complicated.. I have 3 but the oldest is a 22 year old DS, an earning non dependent who lives at home and pays me £200 a month. My DD is 15 (straightforward) and my other DS is 14 but living in residential school due to complex needs so I didn't I input him into the calculator. However I am entitled to claim (and do!) child benefit for him as I buy all his clothes, provide spending money etc.
So I get £134 (I think) 4 weekly in child benefit. And xH pays £100 a month in maintenance. This would be my total income once single.
Will I really get no help with rent?
Can anyone advise at all in the info I've given? I'm a little scared and need to be strong.. Not panicky
