And my parents were far from on the breadline. Both doctors, both working in medicine and academia/the civil service with excellent salaries, and a 6 bed house.
Partly why I had no clue benefits and homeless shelters existed.
See this is the thing; somehow (I can't remember or work out how, nobody was helping me) I eventually came to know about HB, and claimed that and Income Support through the last part of upper sixth.
Until then I'd sofa-surfed around our nice MC suburb with literally no money for 6 months.
And then I didn't apply for uni funding because I didn't know about estrangement rules, so I didn't take up my place , I drifted off alone and set about supporting myself for 3 years ( I DID know I would be considered financially an independent student at 21).
So I tried to support myself on low skilled, low pay jobs @ about £2 ph (early 90s).
I wasn't as unlucky as you and never spent a night without a roof or had anything really catastrophic happen BUT I lived in shitty places and got into dodgy situations and abusive relationships and went without food and never claimed HB while working because I didn't know THAT was allowed. So I was grindingly poor and cold and under-equipped - I just had sheets and a single small saucepan for two or three years; no kettle, no duvet, no blankets.
And I look back and think why did no-one take ownership and refer me at any stage? For support or advice? Even the school? I could have got student finance and gone straight to uni and been safer. But my parents were professionals too. So maybe assumptions were made by onlookers. I don't know. I was never even questioned by anyone about the abuse or the incident that had led to me being homeless at 17. I do wonder whether it's only ever been teens already known to SS who have been likely to be picked up and helped?
I have some involvement with a foyer now but the client group there is largely care leavers, so although I support it, I didn't really see my younger self reflected there. I'd love to now how unusual non-care-leaving homeless teens fending for themselves are.
