Similarly to Vicar, I was placed in a hostel on my 16th birthday after my mum threw me out. I shared a room with the heroin addict and a DV victim. One week later we all got thrown out because the landlady found the addict's needles. I thank my lucky stars that a friends mum let me sleep on their floor for 6 weeks until I got a bedsit on a young persons homeless project.
I moved out of that City but some years later when I went back I saw the heroin addict selling the big issue on the street. That'll stay with me forever.
I don't really know what my point is, watching programmes like that just bring it all back.
