Small, safe spaces.
That is... I went onto the streets to escape poverty, violence and sexual abuse.
For me a hostel was not a safe space, so I didn't even successfully make it onto the first rung of support. It was hostels that distributed information on where to get food and such, so I missed that too.
So there needs to be a better support system for those sleeping rough, and that needs to recognise the flaws in the offerings today and also find better ways to distribute information.
Then, I've made the argument before that we should have a better way to migrate someone off of the street. It's not enough to give a council flat, someone I knew at that time eventually committed suicide because he couldn't cope, fell apart, and suffered from the isolation.
I think instead of that, there should be spaces smaller than a studio apartment that are transition spaces. They should be private, but perhaps clustered so that there is a support network there. People should be given help on how to do things, simple things like how to shop and eat better, how to take care of a home and manage the utilities and bills, how to basically live normally again and construct those routines. How to not shrink into that space and be alone.
I did meet a lot of people with mental illnesses, I don't believe anyone can wave a magic wand and get them off the streets. But we can have the structure in place to help them so that when they are ready, it's possible.
The vast majority of the people on the streets in the UK aren't there because of drugs and alcohol, that's just a visible symptom of a small minority. Most I spoke to had normal lives, good lives, but a trauma occurred and they ended up on the street. There seemed to be a lot of divorced or widowed males. A lot of the young who were physically and/or sexually abused.
Anyhow, a link http://crackandcider.com/ . These people are good, it's no magic wand, but they will take monetary donations and turn it into basic things to help keep people warm and alive even if they are rough-sleeping. I like that they're challenging those misconceptions too.
