"To go home and know you've left them - we've had to tuck women into foil blankets and just say 'see you later' - that can be heartbreaking sometimes."
Dani Brown has just spent hours of her Wednesday evening driving and walking around the streets of Bridgwater, Somerset.
She's an outreach worker with the town's women's centre run by a charity, The Nelson Trust.
Every week she and a colleague go looking for homeless women who may need their help.
They load up a van with supplies from instant noodles and hot water, to underwear, panic alarms and sanitary products, and go out offering practical help and advice.
And Sarah, not her real name, knows what a difference this "brilliant" work can make.
After five years using heroin, shoplifting, having her kids taken into care, and sleeping "in garages, on the streets, in alleyways", she has now been clean for 18 months.
